Laminater av slike skum oppviser en høy grad av brannherdighet, lav røkutvikling ved forbrenning, lav skumsprøhet og høy trykkfasthet.Cellular foams, especially polyurethane foams, are prepared by reacting an organic polyisocyanate, a blowing agent, a catalyst and a polyol mixture, and 10-90% by weight of the polyol used is a polyol mixture prepared by transesterification, using a glycol, of a by-product fraction from the preparation of dimethyl terephthalate, the major part of said fraction comprising 15-70% by weight of dimethyl terephthalate and 85-30% by weight of a mixture of monomethyl terephthalate, biring esters and polymeric materials. Laminates of such foams show a high degree of fire resistance, low smoke development during combustion, low foam embrittlement and high compressive strength.
Description
Oppfinnelsen angår fremstillingen av celleformede skummaterialer, særlig uretanskum. Skummene kan The invention relates to the production of cellular foam materials, in particular urethane foam. The foams can
fremstilles fra et organisk polyisocyanat og en polyolblanding som omfatter transforestringsproduktet av en glykol med en fraksjon fra fremstillingen av dimetyltereftalat. is prepared from an organic polyisocyanate and a polyol mixture comprising the transesterification product of a glycol with a fraction from the preparation of dimethyl terephthalate.
Fremstillingen av skumkarakterisert vedisocyanurat-The production of foam-characterized vedisocyanurate-
og uretanbindinger er velkjent i faget. Generelt fremstilles disse skum ved omsetting av et organisk polyisocyanat med en polyol i nærvær av et esemiddel og en eller flere katalysatorer. Polyesterpolyoler av'mange typer, kan anvendes som polyol-komponentene i fremstillingen av disse skum. and urethane bonds are well known in the art. In general, these foams are produced by reacting an organic polyisocyanate with a polyol in the presence of a blowing agent and one or more catalysts. Polyester polyols of many types can be used as the polyol components in the production of these foams.
US-PS 4 039 487, f.eks., angir bruken av aromatiske polyesterpolyoler for fremstilling av polyisocyanuratskum. Skjønt skummene ifolge dette patentskrift.har god■brannherdighet og lav røkutvikling ved forbrenning, har de forholdsvis høy sprø-het. Videre er polyolene forholdsvis dyre å fremstille. US-PS 4,039,487, for example, discloses the use of aromatic polyester polyols for the production of polyisocyanurate foams. Although the foams according to this patent document have good fire resistance and low smoke generation during combustion, they have relatively high brittleness. Furthermore, the polyols are relatively expensive to produce.
US-PS 4 092 276 angir også bruken av forholdsvis kost-bare, aromatiske polyesterpolyoler i fremstilling av polyisocyanuratskum. En annen ulempe ved disse skum er at de ikke har særlig høy trykkfasthet. Nok et problem ved anvendelsen av aromatiske polyesterpolyoler, særlig de som har lav molekylvekt, er at polyolene er tilbøyelige til å foreligge i fast form ved værelsestemperatur eller er kjennetegnet ved meget høy viskositet og dårlig oppløselighet i harpiksblandinger, hvilket gjør dem vanskelige å håndtere. US-PS 4,092,276 also indicates the use of relatively expensive, aromatic polyester polyols in the production of polyisocyanurate foam. Another disadvantage of these foams is that they do not have particularly high compressive strength. Another problem with the use of aromatic polyester polyols, especially those with low molecular weight, is that the polyols tend to be in solid form at room temperature or are characterized by very high viscosity and poor solubility in resin mixtures, which makes them difficult to handle.
For å avhjelpe de ovenfor nevnte ulemper, har det vært foreslått i US-PS 4 237 238 å anvende i fremstillingen av po-lyisocyanur atskum en mindre mengde av en billig biprodukttype av flytende polyolblanding som fås ved transforestringen, ved anvendelse av en glykol ned molekylvekt på 60-400, av en reak-sjonsproduktrest av dimetyltereftalat-forestret oksydat. Denne rest inneholder lite eller intet dimetyltereftalat. Det er angitt at de fremsti1 te polyisocyanuratskum erkarakterisert veden høy grad av brannherdighet med lav røkutvikling ved forbrenning, lav skumsprøhet og forholdsvis god trykkfasthet. In order to remedy the above-mentioned disadvantages, it has been proposed in US-PS 4,237,238 to use in the production of polyisocyanurate foam a smaller amount of an inexpensive by-product type of liquid polyol mixture obtained by the transesterification, by using a lower molecular weight glycol of 60-400, of a reaction product residue of dimethyl terephthalate-esterified oxidate. This residue contains little or no dimethyl terephthalate. It has been stated that the polyisocyanurate foams produced are characterized by a high degree of fire resistance with low smoke generation during combustion, low foam brittleness and relatively good compressive strength.
Den foreliggende oppfinnelse angår forbedrede celleformede skum, særlig polyuretanskum som har The present invention relates to improved cellular foams, particularly polyurethane foams which have
en kombinasjon av fordelaktige egenskaper innbefattet redusert sprøhet og høy termisk stabilitet og trykkfasthet samt en fremgangsmåte til fremstilling av disse skum. a combination of advantageous properties including reduced brittleness and high thermal stability and compressive strength as well as a method for producing these foams.
Oppfinnelsen er også rettet på et forbedret polyuretanskum som erkarakterisert vedlav sprøhet og brennbarhet og høy trykkfasthet, og en fremgangsmåte til fremstilling av skummet. The invention is also directed to an improved polyurethane foam which is characterized by low brittleness and flammability and high compressive strength, and a method for producing the foam.
Oppfinnelsen angår også polyuretan-skummaterialer,karakterisert veden høy grad av brannherdighet med lav -røkut-vikling og flammespredning ved forbrenning, og dannelsen av en beskyttende, oppsvulmet, forkullet masse over ubrent skum ved forbrenning. The invention also relates to polyurethane foam materials, characterized by the wood's high degree of fire resistance with low smoke emission and flame spread during combustion, and the formation of a protective, swollen, charred mass over unburnt foam during combustion.
Videre angår oppfinnelsen polyuretanskum fremstiltFurthermore, the invention relates to polyurethane foam produced
fra skumdannende materialer som reagerer hurtig for å skaffe høy omsetting til trimer. from foaming materials that react quickly to obtain high conversion to trimer.
Oppfinnelsen omfatter også polymere skummaterialer med lukkede celler, særlig skum som kan anvendes The invention also includes polymeric foam materials with closed cells, in particular foams that can be used
i bygningsplater som er meget isolerende, termisk motstands-dyktige, lydtette, har lav sprøhet og er selvbærende. in building boards that are highly insulating, thermally resistant, soundproof, have low brittleness and are self-supporting.
Oppfinnelsen skaffer således et polyuretanskum som er kjennetegnet ved det som fremgår av kravene. The invention thus provides a polyurethane foam which is characterized by what appears in the claims.
Oppfinnelsen omfatter videre en polyolblanding til anvendelse i fremstilling av polymere skummaterialer, særlig polyuretanskum som har redusert sprøhet og høy termisk stabilitet og trykkfasthet, og en fremgangsmåte til fremstilling av polyolblandingen. The invention further comprises a polyol mixture for use in the production of polymeric foam materials, in particular polyurethane foam which has reduced brittleness and high thermal stability and compressive strength, and a method for producing the polyol mixture.
Ved den foreliggende oppfinnelseIn the present invention
fremstilles en forbedret, celleformetan improved, cell-shaped is produced
polymer ved at et organisk polyisocyanat omsettes med den meget reaktive polyesterpolyol ifølge oppfinnelsen i nærvær av et esemiddel og en eller flere katalysatorer. Polyesterpolyolen omfatter en polyolblanding fremstilt ved transforestring, ved anvendelse av en glykol, av en fraksjon som fås fra fremstillingen av dimetyltereftalat, idet hoveddelen av den nevnte fraksjon omfatter en blanding av dimetyltereftalat, monometyltereftalat, birinc-estere og oligomerer av tereftalatet og biring-esterne. polymer by reacting an organic polyisocyanate with the highly reactive polyester polyol according to the invention in the presence of a blowing agent and one or more catalysts. The polyester polyol comprises a polyol mixture produced by transesterification, using a glycol, of a fraction obtained from the production of dimethyl terephthalate, the main part of said fraction comprising a mixture of dimethyl terephthalate, monomethyl terephthalate, birinc esters and oligomers of the terephthalate and the birinc esters.
Oppfinnelsen angår særlig et polyuretanskum.karakterisert vedat det er fremstilt ved at der som 10-90 vektprosent av polyolen benyttes en polyolblanding fremstilt ved transforestring av en biproduktfraks jon fra fremstillingen av dimetyltereftalat med en glykol med molekylvekt på 60- The invention relates in particular to a polyurethane foam, characterized in that it is produced by using as 10-90 percent by weight of the polyol a polyol mixture produced by transesterification of a by-product fraction from the production of dimethyl terephthalate with a glycol with a molecular weight of 60
400, idet den nevnte fraksjon omfatter 15-70 vektprosent dimety11erefta1 at, mens resten består av en blanding av monometyltereftalat. bi r ing-estere, polymere materialer, tereftal syre. organiske syresalter og aske. 400, the said fraction comprising 15-70 percent by weight of dimethyl etherephthalate, while the remainder consists of a mixture of monomethyl terephthalate. bi r ing esters, polymeric materials, terephthalic acid. organic acid salts and ash.
Den industrielle fremstilling av dimetyltereftalat an-vender p-xylen som startmateriale og omfatter oksidasjons- og forestringsreaksjoner (med metanol). Fremgangsmåten fører til dannelsen av meget komplekse blandinger av produkter . US-PS The industrial production of dimethyl terephthalate uses p-xylene as starting material and includes oxidation and esterification reactions (with methanol). The process leads to the formation of very complex mixtures of products. US PS
3 647 759 angir generelt fremgangsmåten og beskriver særlig 3 647 759 generally states the method and describes in particular
den komplekse spylte (purged) rest som dannes derved. Denne rest, som typisk inneholder 0-6 vektprosent dimetyltereftalat kalles "dimetyltereftalat-forestret oksidatrest" i US-PS 3 647 759. the complex purged residue that is formed thereby. This residue, which typically contains 0-6% by weight of dimethyl terephthalate, is called "dimethyl terephthalate-esterified oxide residue" in US-PS 3,647,759.
Det er denne dimetyltereftalat-forestrede oksidatrest som omsettes med en glykol ifølge US PS 4 237 238 for fremstilling av den transforestrede polyolblanding i det nevnte patentskrift. Det er nå overraskende funnet at en mer reaktiv polyolblanding enn den som er beskrevet i det nevnte patentskrift kan fremstilles ved å transforestre med en glykol en fraksjon fra fremstillingen av dimetyltereftalat, som har et vesentlig høyere innhold av dimetyltereftalat enn den spylte rest ifølge US-PS 3 647 759 og 4 237 238. Videre er det funnet at polyisocyanuratskum fremstilt med en mindre mengde av denne meget reaktive trans forestrede polyolblanding ifølge oppfinnelsen, har overlegne trykkfastheter som overstiger de trykkfastheter som fås ved skum fremstilt ifølge US-PS 4 237 238. It is this dimethyl terephthalate-esterified oxide residue that is reacted with a glycol according to US PS 4,237,238 to produce the transesterified polyol mixture in the aforementioned patent document. It has now surprisingly been found that a more reactive polyol mixture than that described in the aforementioned patent can be produced by transesterifying with a glycol a fraction from the production of dimethyl terephthalate, which has a significantly higher content of dimethyl terephthalate than the rinsed residue according to US-PS 3 647 759 and 4 237 238. Furthermore, it has been found that polyisocyanurate foam produced with a smaller amount of this highly reactive trans-esterified polyol mixture according to the invention has superior compressive strengths that exceed the compressive strengths obtained with foam produced according to US-PS 4 237 238.
Biprodukter fra dimetyltereftalatfremstilling er meget komplekse og kan variere meget i sammensetning i henhold til de betingelser som anvendes i oksidasjonstrinnene i prosessen etc. Den fraksjon som er funnet å være nyttig i den foreliggende oppfinnelse har imidlertid en generell karakteristikk som tjener til å skille den klart fra de tidligere anvendte reste-biprodukter, nemlig dens betydelige innhold av dimetyl-teref talat som tidligere nevnt. Typisk kan dimetyltereftalat omfatte 15-70 vektprosent av denne fraksjon og omfatter fortrinnsvis 20-60, helst 40-60 vektprosent av fraksjonen. Dimetyl-tereftalatet finnes generelt i kombinasjon med 1-10 vektprosent monometyltereftalat, og resten av fraksjonen omfatter en blanding av tereftalsyre, bifenyl- og andre fenylestere, andre substituerte bifenyler, polymere materialer og den eller de katalysatorer som anvendes for å fremme oksidasjons- og for-estringsreaksjonene. By-products from dimethyl terephthalate production are very complex and can vary greatly in composition according to the conditions used in the oxidation steps of the process etc. However, the fraction found to be useful in the present invention has a general characteristic which serves to distinguish it clearly from the previously used residual by-products, namely its significant content of dimethyl terephthalate as previously mentioned. Typically, dimethyl terephthalate can comprise 15-70 percent by weight of this fraction and preferably comprises 20-60, preferably 40-60 percent by weight of the fraction. The dimethyl terephthalate is generally found in combination with 1-10% by weight of monomethyl terephthalate, and the rest of the fraction comprises a mixture of terephthalic acid, biphenyl and other phenyl esters, other substituted biphenyls, polymeric materials and the catalyst(s) used to promote oxidation and -the esterification reactions.
En særlig nyttig, høytkokende fraksjon fra fremstillingen av dimetyltereftalat har den følgende tilnærmede sammensetning : A particularly useful, high-boiling fraction from the production of dimethyl terephthalate has the following approximate composition:
Den transforestrede polyolblanding ifølge oppfinnelsen fremstilles ved oppvarming av den ovenfor angitte biproduktfraksjon med en transforestringsglykol i henhold til de frem-gangsmåter som er beskrevet i US-PS 3 647 759. Transforestrings-trinnet er ganske enkelt erstatningen av de ikke-hydroksylhold-ige karbometoksygrupper i de forskjellige aromatiske estere av fraksjonen med glykolmidler for oppnåelse av ende-hydroksyl- The transesterified polyol mixture according to the invention is produced by heating the above-mentioned byproduct fraction with a transesterification glycol according to the methods described in US-PS 3,647,759. The transesterification step is simply the replacement of the non-hydroxyl-containing carbomethoxy groups in the various aromatic esters of the fraction with glycol agents to obtain end-hydroxyl-
grupper.groups.
Tranforestringsglykolen kan være alifatisk, cykloalifa-tisk eller aromatisk. Glykolen er fortrinnsvis en alifatisk, toverdig alkohol som helst har 2-16 karbonatomer. Molekylvekten av denne foretrukne glykol ligger med fordel i området 60-400. Eksempler på egnede glykoler omfatter eten-, oksydi-eten-, propen-, oksydipropen-, buten-, penten- og heksylengly-koler, og isomere former derav; polyoksyalkenglykolene såsom polyoksyeten- og polyoksypropenglykoler som helst har en molekylvekt på 150-400; 1,8-oktandiol, 1,4-bis-hydroksymetylcyklo-heksan, 2-metyl-l,3-propandiol, dimetylol-dicyklopentadien, 1,3-cykloheksandiol og 1,4-cykloheksandiol. Transforestrings-glykolene kan selvsagt anvendes som en blanding av flere dioler. Glykolene kan innbefatte substituenter som er inerte i transforestringsreaksjonen, som f.eks. klor- og bromsubstitu--enter. The transesterification glycol can be aliphatic, cycloaliphatic or aromatic. The glycol is preferably an aliphatic, dihydric alcohol preferably having 2-16 carbon atoms. The molecular weight of this preferred glycol is advantageously in the range 60-400. Examples of suitable glycols include ethylene, oxydiethylene, propene, oxydipropene, butene, pentene and hexylene glycols, and isomeric forms thereof; the polyoxyalkene glycols such as polyoxyethylene and polyoxypropylene glycols which preferably have a molecular weight of 150-400; 1,8-octanediol, 1,4-bis-hydroxymethylcyclohexane, 2-methyl-1,3-propanediol, dimethylol-dicyclopentadiene, 1,3-cyclohexanediol and 1,4-cyclohexanediol. The transesterification glycols can of course be used as a mixture of several diols. The glycols may include substituents which are inert in the transesterification reaction, such as e.g. chlorine and bromine substituents.
To foretrukne glykoler er etenglykol og dietenglykol,Two preferred glycols are ethylene glycol and diethylene glycol,
og den sistnevnte er mer foretrukket. and the latter is more preferred.
Transforestringsreaksjonen blir passende utført ved at biproduktfraksjonen fra dimetyltereftalatproduksjonen blandes med glykolen som fortrinnsvis foreligger i en mengde som er større enn den som er nødvendig for omsetting med fraksjonen, på grunnlag av støkiometri, og at reaksjonen utføres under vanlige transforestringsbetingelser som er velkjent og beskrevet i tidligere kjent teknikk. Som'et eksempel kan transforestringen utføres i fravær av et flytende reaksjonsmedium bestå-ende av materialer andre enn glykolen og biproduktfraksjonen, under en strøm av nitrogen og ved atmosfæretrykk og temperaturer på 150-250°C i en periode på 1-10 timer. Reaksjonen an-ses å være stort sett fullstendig når dannelsen av metanol opp-hører. Under reaksjonsperioden blir det metanol som dannes, fj ernet. The transesterification reaction is conveniently carried out by mixing the by-product fraction from the dimethyl terephthalate production with the glycol, which is preferably present in an amount greater than that required for reaction with the fraction, on the basis of stoichiometry, and that the reaction is carried out under normal transesterification conditions which are well known and described in previous known technique. As an example, the transesterification can be carried out in the absence of a liquid reaction medium consisting of materials other than the glycol and the by-product fraction, under a stream of nitrogen and at atmospheric pressure and temperatures of 150-250°C for a period of 1-10 hours. The reaction is considered to be largely complete when the formation of methanol ceases. During the reaction period, the methanol that is formed is removed.
Transforestringsreaksjonen blir normalt katalysert. Generelt har fraksjonen fra fremstillingen av dimetyltereftalat et katalysatorinnhold som er virksomt for transforestringen og som vil fremme den foreliggende reaksjon. Hvis imidlertid en slik katalysator ikke foreligger eller ikke tilstrekkelig av den foreligger, blir tilstrekkelig transforestringskataly- sator tilsatt til reaksjonsblandingen for å fremme reaksjonen på egnet måte. En hvilken som helst vanlig transforestrings-katalysator (enkeltforbindelse eller blanding av forbindelser) kan anvendes. The transesterification reaction is normally catalyzed. In general, the fraction from the preparation of dimethyl terephthalate has a catalyst content which is effective for the transesterification and which will promote the present reaction. If, however, such a catalyst is not available or not enough of it is available, sufficient transesterification catalyst is added to the reaction mixture to promote the reaction in a suitable manner. Any common transesterification catalyst (single compound or mixture of compounds) can be used.
Skjønt den transforestrede polyolblanding ifølge oppfinnelsen kan anvendes uten filtrering, foretrekkes det å filtrere blandingen før den senere anvendelse, f.eks. i skumfremstil-linger. Alternativt kan biproduktfraksjonen filtreres før den transforestres. Fjerning av metallsalt oppnås ved filtreringen. Although the transesterified polyol mixture according to the invention can be used without filtration, it is preferred to filter the mixture before its subsequent use, e.g. in foam preparations. Alternatively, the by-product fraction can be filtered before being transesterified. Removal of metal salt is achieved by filtration.
Egenskapene av de transforestrede polyolblandinger Ifølge oppfinnelsen faller innen temmelig vide områder, pga. den komplekse og variable natur av selve de dimetyltereftalat-holdige fraksjoner. Således ligger viskositetene (Brookfield) av polyolblandingene målt. i Pa.s ved 25°C i det nokså vide område fra ca. 0,5 til "ca-.- 5.00, fortrinnsvis fra ca. 0,5 til ga. 10 og helst fra ca-. 0 ,'7 til ca. 2,5, hydroksyltallet ligger i området 150-950, fortrinnsvis 280-650, og helst 350-510, og syre-tallet ligger i området 0,2-40, helst 0,2-10. The properties of the transesterified polyol mixtures according to the invention fall within rather wide areas, due to the complex and variable nature of the dimethyl terephthalate-containing fractions themselves. Thus the viscosities (Brookfield) of the polyol mixtures are measured. in Pa.s at 25°C in the fairly wide range from approx. 0.5 to "ca-.- 5.00, preferably from about 0.5 to ga. 10 and most preferably from about-. 0.'7 to about 2.5, the hydroxyl number is in the range 150-950, preferably 280- 650, and preferably 350-510, and the acid number is in the range 0.2-40, preferably 0.2-10.
Glykolen anvendes fortrinnsvis i overskudd i transforestringsreaksjonen, slik at der ved slutten av reaksjonen er et overskudd av transforestringsglykol i polyolblandingen ifølge oppfinnelsen. Dette overskudd kan variere innen vide grenser, men ligger fortrinnsvis i området 5-40 vektprosent regnet på polyolblandingen. The glycol is preferably used in excess in the transesterification reaction, so that at the end of the reaction there is an excess of transesterification glycol in the polyol mixture according to the invention. This excess can vary within wide limits, but is preferably in the range of 5-40 percent by weight based on the polyol mixture.
En særlig foretrukket polyolblanding ifølge oppfinnelsen erkarakterisert veden viskositet i Pa.s ved 25°C på 0,7-2,5, et fritt dietenglykolinnhold på 10-30 vektprosent regnet på blandingen, et hydroksyltall i området 350-468 og et syretall på 0,2-10. A particularly preferred polyol mixture according to the invention is characterized by a wood viscosity in Pa.s at 25°C of 0.7-2.5, a free diethylene glycol content of 10-30 percent by weight calculated on the mixture, a hydroxyl number in the range 350-468 and an acid number of 0 ,2-10.
Skjønt polyolblandingen ifølge oppfinnelsen lett kan fremstilles som fluide materialer, særlig ved å anvende et overskudd av glykol-transforestringsmiddel og etterlate rest-glykol i blandingene, kan ytterligere fortynningsmidler anvendes sammen med polyolblandingene. Inerte fortynningsmidler kan anvendes, men det foretrekkes som regel å anvende flytende polyoler. I en foretrukket utførelsesform av oppfinnelsen, kan derfor dioler såsom etenglykol, dietenglykol, dipropenglykol eller hvilken som helst av de andre glykoler som er angitt ovenfor som transforestringsmidler, tilsettes i et senere trinn for å redusere viskositeten av polyolblandingen. Although the polyol mixture according to the invention can easily be produced as fluid materials, in particular by using an excess of glycol transesterification agent and leaving residual glycol in the mixtures, additional diluents can be used together with the polyol mixtures. Inert diluents can be used, but it is generally preferred to use liquid polyols. In a preferred embodiment of the invention, therefore, diols such as ethylene glycol, diethylene glycol, dipropene glycol or any of the other glycols listed above as transesterification agents can be added in a later step to reduce the viscosity of the polyol mixture.
For reduksjon av viskositeten anvendes disse fortynningsmidler generelt bare i mindre mengder som f.eks. i området 1-40 vektprosent, fortrinnsvis 5-30 vektprosent, regnet på polyolblandingen. Det ligger imidlertid også innen oppfinnelsens omfang å danne diolblandinger hvor den transforestrende glykol foreligger i større mengder. Innholdet av trans forestringsglykol i blandingen kan økes gradvis til det punkt hvor den er den største bestanddel, og den transforestrede blanding ifølge oppfinnelsen foreligger bare i en mindre mengde, f.eks. i området 1-20 vektprosent, regnet på den transforestrende glykol. To reduce the viscosity, these diluents are generally only used in small quantities, such as e.g. in the range 1-40% by weight, preferably 5-30% by weight, based on the polyol mixture. However, it is also within the scope of the invention to form diol mixtures in which the transesterifying glycol is present in larger quantities. The content of trans esterification glycol in the mixture can be gradually increased to the point where it is the largest component, and the transesterification mixture according to the invention is present only in a smaller amount, e.g. in the range 1-20 percent by weight, calculated on the transesterifying glycol.
Polyolblandingen ifølge oppfinnelsen kan anvendes i fremstillingen av både celleformede og ikke-celleformede polymerer. De sistnevnte polymerer såsom polyisocyanuratene og polyuretan-ene, kan fremstilles ved anvendelse av standardteknikker som er kjent for fagfolk. Polyolblandingene er særlig nyttige i fremstillingen av polyisocyanuratskum og polyuretanskum. Disse skum kan fremstilles ved at det organiske polyisocyanat blandes sammen med polyolblandingen, katalysatoren og esemiddelet ved temperaturer i området 0-150°C. The polyol mixture according to the invention can be used in the production of both cellular and non-cellular polymers. The latter polymers, such as the polyisocyanurates and polyurethanes, can be prepared using standard techniques known to those skilled in the art. The polyol mixtures are particularly useful in the production of polyisocyanurate foam and polyurethane foam. These foams can be produced by mixing the organic polyisocyanate with the polyol mixture, the catalyst and the blowing agent at temperatures in the range 0-150°C.

Særlig nyttige er polymetylenpolyfenyl isocyanater. Disse isocyanater fremstilles ved vanlige metoder som er kjent i faget såsom fosgenering av det tilsvarende organiske amin.

Particularly useful are polymethylene polyphenyl isocyanates. These isocyanates are prepared by common methods known in the art such as phosgenation of the corresponding organic amine.

The speeds of the pumps 17, 18 and 19 are regulated to provide the desired ratios between the ingredients in the tanks 11, 12
og 13. Disse ingreuienser passerer henholdsvis gjennom rørled-ninger 20, 21 og 22 samt rørledninger 23, 24 og 25, hvoretter de blandes i blandehodet 29 og slippes ut derfra. Alternativt kan rørledningene 21 og 22 kombineres før blandehodet. Trekkvalsene 38, 39 som hver har en bøyelig ytre kappe 40, 41, bringes til å rotere i .retningen vist ved pilene ved hjelp av en kraftkilde (ikke vist). På grunn av rotasjonen av trekkvalsene 38, 39, blir det nedre belegningsmateriale trukket fra rullen 30 mens det øvre belegningsmateriale blir trukket fra rullen and 13. These ingredients respectively pass through pipelines 20, 21 and 22 as well as pipelines 23, 24 and 25, after which they are mixed in the mixing head 29 and discharged from there. Alternatively, the pipelines 21 and 22 can be combined before the mixing head. The drawing rollers 38, 39, each having a flexible outer jacket 40, 41, are caused to rotate in the direction shown by the arrows by means of a power source (not shown).

Fremstilling av trans forestrede polyolblandingerProduction of trans-esterified polyol mixtures
Dette eksempel viser fremstillingen av forskjellige transforestrede polyolblandinger ifølge oppfinnelsen. This example shows the preparation of various transesterified polyol mixtures according to the invention.
En dimentyltereftalat-holdig biproduktfraksjon (DMT-HBR) fra fremstillingen av dimetyletereftalat levert av E.I. duPont de Nemours&Co., Inc. under handelsbetegnelsen "DMT-HBR", ble underkastet en serie på tre transforestringsreaksjoner ved anvendelse av dietenglykol (DEG) som transforestringsglykolen A dimenthyl terephthalate-containing by-product fraction (DMT-HBR) from the preparation of dimethyl ether phthalate provided by E.I. duPont de Nemours&Co., Inc. under the trade name "DMT-HBR", was subjected to a series of three transesterification reactions using diethylene glycol (DEG) as the transesterification glycol
i hver reaksjon, for fremstilling av polyolblandinger A, B og C ifølge oppfinnelsen (se tabell 1). Mengdene av de ingredienser som ble anvendt .i hver reaksjon inklusiv mengden katalysator, er angitt i tabell 1. Hver reaksjon ble utført under nitrogenspyling ved en temperatur på 180-230°C, for å gi den mengde metanol som er vist i tabell 1. I reaksjon nr. 1 ble 66 g dietenglykol vakuumdestillert fra den trans forestrede polyolblanding . in each reaction, for the production of polyol mixtures A, B and C according to the invention (see table 1). The amounts of the ingredients used in each reaction, including the amount of catalyst, are given in Table 1. Each reaction was carried out under a nitrogen purge at a temperature of 180-230°C, to give the amount of methanol shown in Table 1. In reaction no. 1, 66 g of diethylene glycol were vacuum distilled from the trans-esterified polyol mixture.
Den transforestrede polyolblanding fremstilt ved reaksjon 3 (polyolblanding C), ble funnet å inneholde 7,8 vektprosent faststoffer regnet på vekten av DMT-HBR, etter filtrering ved 100°C. Et faststoffinnhold på 5% (fint, grått pulver) ble funnet etter en metylenklorid-vask. Faststoffene ble ved ana-lyse funnet å inneholde mangan- og koboltsalter av tereftalsyre . The transesterified polyol mixture prepared by reaction 3 (polyol mixture C) was found to contain 7.8 weight percent solids based on the weight of DMT-HBR, after filtration at 100°C. A solids content of 5% (fine, gray powder) was found after a methylene chloride wash. The solids were found by analysis to contain manganese and cobalt salts of terephthalic acid.
Noen ytterligere egenskaper av de fremstilte, transforestrede polyolblandinger er vist nederst i tabell 1. Det kan ses at den fysiske tilstand av den resulterende polyolblanding kan forandres fra et glass til en væske ved anvendelse av et større overskudd dietenglykol i transforestringsreaksjonen. Some further properties of the produced transesterified polyol mixtures are shown at the bottom of Table 1. It can be seen that the physical state of the resulting polyol mixture can be changed from a glass to a liquid by using a larger excess of dietene glycol in the transesterification reaction.
