Klorf luoralkankomposisjoner. Chloral luoralcan compositions.
Foreliggende oppfinnelse vedrører klorfluor-alkankomposisj oner. Mer spesielt vedrører den komposisjoner som inneholder et klorf luoral-kan av methan- eller ethanrekken og forbindelser som hemmer reaksjon av klorfluoralkan med polyoler og aminer som anvendes ved fremstillingen av polyurethanskum. The present invention relates to chlorofluoroalkane compositions. More particularly, it relates to compositions containing a chlorofluoroalkane of the methane or ethane series and compounds that inhibit the reaction of chlorofluoroalkane with polyols and amines used in the production of polyurethane foam.
Lavtkokende klorfluoralkaner, særlig tri-klorfluormethan, anvendes i stor utstrekning som esemidler ved fremstilling ov polyurethanskum ved reaksjon mellom polyoler og polyfunksjonelle isocyanater. En foretrukket fremgangs-måte for fremstilling av polyurethanskum er å innføre klorfluoralkanesemidlet i den prinsi-pielle polyolkomponent sammen med kryss-bin-dende eller fornettende midler som f. eks. hydroksyalkylaminer, glycerol eller 1,3-propylen-glykol, katalysatorer, vanligvis tertiære aminer og eventuelt vann, som virker som et ytter-ligere esemiddel, og blandingen blandes derpå med isocyanatet. Reaksjonsvarmen ved reaksjonen av polyol (og vann hvis dette er til stede) med isocyanatet fordamper esemidlet og frembringer den ønskede cellestruktur i poly-urethanproduktet. Low-boiling chlorofluoroalkanes, especially trichlorofluoromethane, are used to a large extent as blowing agents in the production of polyurethane foam by reaction between polyols and polyfunctional isocyanates. A preferred procedure for the production of polyurethane foam is to introduce the chlorofluoroalkanes agent into the main polyol component together with cross-linking or cross-linking agents such as, e.g. hydroxyalkylamines, glycerol or 1,3-propylene glycol, catalysts, usually tertiary amines and optionally water, which acts as an additional emulsifying agent, and the mixture is then mixed with the isocyanate. The reaction heat from the reaction of the polyol (and water if present) with the isocyanate evaporates the blowing agent and produces the desired cell structure in the polyurethane product.
Skjønt klorfluoralkaner generelt er kjemisk inerte eller indifferente har det vist seg at de kan reagere langsomt med polyoler og også med aminer, særlig med hydroksyalkylaminer med lav molekylvekt som anvendes som fornettende midler, særlig triethanolamin, hvor-under det frigjøres hydrogenhalogenid, dannel-sen av en utfelning og misfarvning av blandingen Denne reaksjon er særlig mindre tilfreds-stillende hvis det er ønskelig å forsende eller å lagre ferdig for bruk ved ett eller annet be-stemt tidspunkt klorfluoralkanet i blanding med polyolen og eventuelt de reaktive fornettende midler og det er blitt foreslått, f. eks. i det britiske patent 1 009 041 å hemme reaksjonen, mellom klorfluoralkaner og primære og sekundære polyoler ved å tilsette til komposisjoner som inneholder enten klorfluoralkan eller også polyol, visse spesifikke olefiniske forbindelser, f. eks. isopren og visse terpener, vinylforindelser og akrylforbindelser. Although chlorofluoroalkanes are generally chemically inert or indifferent, it has been shown that they can react slowly with polyols and also with amines, especially with low molecular weight hydroxyalkylamines used as crosslinking agents, especially triethanolamine, during which hydrogen halide is released, the formation of a precipitation and discoloration of the mixture. This reaction is particularly less satisfactory if it is desired to ship or to store ready for use at one or another specified time the chlorofluoroalkane in mixture with the polyol and possibly the reactive crosslinking agents and it has been proposed , e.g. in the British patent 1 009 041 to inhibit the reaction, between chlorofluoroalkanes and primary and secondary polyols by adding to compositions containing either chlorofluoroalkane or also polyol, certain specific olefinic compounds, e.g. isoprene and certain terpenes, vinyl derivatives and acrylic compounds.
Vi har nu funnet at reaksjonen av klor-fluoralkanesemidler med polyoler og aminer i polyurethanskum-esesysterner kan hemmes mer effektivt ved å innføre i komposisjonene som inneholder enten klorfluoralkan eller klorfluoralkan og polyol en liten del av et medlem ut-valgt fra visse spesifikke forbindelser som skal angis i det følgende. We have now found that the reaction of chlorofluoroalkanes agents with polyols and amines in polyurethane foam esters can be inhibited more effectively by introducing into the compositions containing either chlorofluoroalkane or chlorofluoroalkane and polyol a small portion of a member selected from certain specific compounds which shall specified in the following.
I henholdt til foreliggende oppfinnelse til-veiebringes således en klorfluoralkanpolyolkom-posisjon, eventuelt inneholdende et amin og som skal brukes til polyurethanskumfremstilling og som er tilsatt en inhibitor for å hindre klorfluoralkanets reaksjon med primære og sekundære polyoler og eventuelt aminer, hvilken inneholder klorfluoralkan av methan- eller ethanrekken, og komposisjonen er karakterisert ved at det som inhibitor anvendes 0,05 til 5 vektprosent av en ester av salicylsyre, azobenzen, p-aminoazobenzen, pyrrol, N-alkylpyrroler, eugenol, isoeugenol, hydrazin eller substituerte hydraziner av strukturformelen R1(R2)N.NH2 og RjHN.NHR, i hvilken formel R[ er et alkyl-, karboksylalkyl- aryl-, alkaryl- eller aralkylradikal og R2 er det samme som R, eller et hydrogenatom. According to the present invention, a chlorofluoroalkane polyol composition is thus provided, possibly containing an amine and which is to be used for polyurethane foam production and to which an inhibitor has been added to prevent the chlorofluoroalkane's reaction with primary and secondary polyols and possibly amines, which contains chlorofluoroalkane of methane or the ethane series, and the composition is characterized in that 0.05 to 5% by weight of an ester of salicylic acid, azobenzene, p-aminoazobenzene, pyrrole, N-alkylpyrroles, eugenol, isoeugenol, hydrazine or substituted hydrazines of the structural formula R1 (R2 )N.NH2 and RjHN.NHR, in which formula R[ is an alkyl, carboxylalkyl-aryl, alkaryl or aralkyl radical and R2 is the same as R, or a hydrogen atom.
Komposisjonen i henhold til oppfinnelsen kan dessuten inneholde trietanolamin som fornettende middel. The composition according to the invention can also contain triethanolamine as a cross-linking agent.
En klorfluoralkankomposisjon i henhold til oppfinnelsen kan inneholde mer enn ett klorfluoralkan av methan- eller ethanrekken. Oppfinnelsen er mest fordelakig i forbindelse med komposisjoner som inneholder triklorfluor-methan. A chlorofluoroalkane composition according to the invention may contain more than one chlorofluoroalkane of the methane or ethane series. The invention is most advantageous in connection with compositions containing trichlorofluoromethane.
Eksempler på egnede substituerte hydraziner for bruk i komposisjoner i henhold til oppfinnelsen er 1,1-dimetylhydrazin, hydrazin-mo-noethylkaroksylat, fenyl-hydrazin, hydrazoben-zen og hydrazotoluen. Når selve hydrazinet anvendes, kan det tilsettes til komposisjonen i form av det lett tilgjengelige hydrat. Det skal bemerkes at aromatiske f. eks. fenylhydrazin, har en meget lav oppløselighet i klorfluoralkanet alene, slik at komposisjoner som består av disse to komponenter, bare må omrøres godt for å få jevn blanding av den eventuelt faste fase før bruken. Når polyolkomponenten også er til stede, er de aromatiske hydraziner full-stendig oppløselige i blandingen ved alle nyt-tige konsentrasjoner. Examples of suitable substituted hydrazines for use in compositions according to the invention are 1,1-dimethylhydrazine, hydrazine monoethylcarboxylate, phenylhydrazine, hydrazobenzene and hydrazotoluene. When the hydrazine itself is used, it can be added to the composition in the form of the readily available hydrate. It should be noted that aromatic e.g. phenylhydrazine, has a very low solubility in the chlorofluoroalkane alone, so that compositions consisting of these two components only need to be stirred well to obtain an even mixture of the possibly solid phase before use. When the polyol component is also present, the aromatic hydrazines are completely soluble in the mixture at all useful concentrations.
Polyolene som anvendes i komposisjonene i henhold til oppfinnelsen kan være ett eller flere av de vanligvis anvendte for fremstilling av polyurethanskum ved reaksjon med et poly-funksjonelt isocyanat i nærvær av et klorfluoralkan-esemiddel. De kan være av den art som oppviser ether-, ester, amid eller aminbindinger slik som beskrevet f. eks. i det nevnte britiske patent 1 009 041 og i britisk patent 980 292. Som eksempler på disse fire typer av polyol skal nev-nes ether kondenseringsprodukter av alkylenoksyder med flerverdige alkoholer, som f. eks. sukkeralkoholer, trimethylolpropan og glycerol, estere av dikarboksylsyrer og polyalkylenglyko-ler, amidkondenseringsprodukter av flerverdige alkoholer og polyfunksjonelle isocyanater som The polyols used in the compositions according to the invention may be one or more of those usually used for the production of polyurethane foam by reaction with a polyfunctional isocyanate in the presence of a chlorofluoroalkanesizing agent. They can be of the kind that exhibit ether, ester, amide or amine bonds as described, e.g. in the aforementioned British patent 1 009 041 and in British patent 980 292. As examples of these four types of polyol, mention must be made of ether condensation products of alkylene oxides with polyhydric alcohols, such as e.g. sugar alcohols, trimethylolpropane and glycerol, esters of dicarboxylic acids and polyalkylene glycols, amide condensation products of polyhydric alcohols and polyfunctional isocyanates such as
f. eks. tolyen-di-isocyanat og kondenseringsprodukter av alkylenoksyder med diaminer og e.g. toluene diisocyanate and condensation products of alkylene oxides with diamines and
triaminer. Polyoler av den sistnevnte type, f. triamines. Polyols of the latter type, e.g.
eks. N,N,N'N'-tetrakis(2-hydroksypropyl)-ethyl-endiamin, kan særlig innføres i komposisjonene e.g. N,N,N'N'-tetrakis(2-hydroxypropyl)-ethyl-enediamine, can especially be introduced into the compositions
sammen med andre polyoler for å medvirke along with other polyols to assist
til en viskositetsøkning ved de tidligere trinn av skumningsprosessen som følge av deres fornettende egenskaper. to a viscosity increase at the earlier stages of the foaming process as a result of their cross-linking properties.
Oppfinnelsen skal klargjøres nærmere ved de følgende eksempler. Eldningsforsøk ble ut-ført ved 40 °C i glasskolber under anvendelse av tilbakeløpskondensatorer, og også ved 40°C og ved temperaturer opp til 80°C for å påskynne forsøkene i fortinnede stålbeholdere og lukket The invention shall be clarified in more detail by the following examples. Aging experiments were carried out at 40°C in glass flasks using reflux condensers, and also at 40°C and at temperatures up to 80°C to speed up the experiments in tinned steel containers and closed
med fortinnede lokk, med klorfluoralkan, med with tinned lids, with chlorofluoroalkane, with
og uten stabiliseringsmiddel i blanding med forskjellige polyoler. Stabiliseringsmidler som anvendes i henhold til oppfinnelsen ble under-søkt og sammenlignet med stabiliseringsmidler av kjent art, nemlig olefiniske forbindelser som er foreslått som stabiliseringsmidler i det britiske patent 1 009 041 og forbindelser som oppviser keto-enoltautomerisme slik som er foreslått som stabiliseringsmidler i det tyske patent 1 188 277. Reaksjonen i blandingene ble vurdert and without stabilizer in a mixture with different polyols. Stabilizers used according to the invention were investigated and compared with stabilizers of a known kind, namely olefinic compounds which are proposed as stabilizers in the British patent 1 009 041 and compounds which exhibit keto-enol tautomerism as proposed as stabilizers in the German patent 1 188 277. The reaction in the mixtures was assessed

I de følgende tabeller er polyol A kon-denseringsproduktet av 1 mol sorbitol med 10 mol propylenoksyd, som selges av firmaet Atlas Powder Co. under navnet «Atlas-G2410» («Atlas» er et registrert varemerke). Polyol B er et kondenseringsprodukt av triethanolamin med propylenoksyd, med en hydroksylverdi av ca. 450 mg KOH/g og en viskositet av ca. 350 centipoiser. Polyol C er et kondenseringsprodukt av trimethylolpropan med propylenoksyd med en hydroksylverdi av ca. 540 mg KOH/g og en viskositet av ca. 1800 centipoiser. I enkelte av kom - posisjonene ble blandinger av polyol A, B eller C med små mengder av handelskvalitet av triethanolamin eller N,N,N',N'-tetrakis(2-hyd-roksypropyl)-ethylendiamin (tilgjengelig i han-delen under det registrerte merket «Quadrol») som fornettende midler og/eller små mengder av vann, prøvet med hensyn på reaksjon med klorfluoralkan, slik som vist i tabellene 1, 3, 5, 6, 9 og 10. Prosentangivelser er basert på vekt. Utseendet ved starten av komposisjonene som inneholdt polyol A var meget blek, og slike som inneholdt polyol B var blekgule, og slike som inneholdt polyol C var nesten farveløse. In the following tables, polyol A is the condensation product of 1 mole of sorbitol with 10 moles of propylene oxide, which is sold by Atlas Powder Co. under the name "Atlas-G2410" ("Atlas" is a registered trademark). Polyol B is a condensation product of triethanolamine with propylene oxide, with a hydroxyl value of approx. 450 mg KOH/g and a viscosity of approx. 350 centipoise. Polyol C is a condensation product of trimethylolpropane with propylene oxide with a hydroxyl value of approx. 540 mg KOH/g and a viscosity of approx. 1800 centipoise. In some of the compositions, mixtures of polyol A, B or C with small amounts of commercial grade triethanolamine or N,N,N',N'-tetrakis(2-hydroxypropyl)-ethylenediamine (available in the male section under the registered trademark "Quadrol") as cross-linking agents and/or small amounts of water, tested for reaction with chlorofluoroalkane, as shown in Tables 1, 3, 5, 6, 9 and 10. Percentages are based on weight. The initial appearance of the compositions containing polyol A was very pale, those containing polyol B were pale yellow, and those containing polyol C were almost colorless.
