Description

  

  Verfahren zur Herstellung neuer epoxydgruppenhaltiger Acetale    Gegenstand des vorliegenden Patentes ist ein       Verfahren    zur Herstellung neuer,     mindestens    zwei  Epoxydgruppen enthaltender Acetale der Formel  
EMI0001.0002     
    worin X1 und X2 Wasserstoffatome oder Methyl  gruppen und Z einen mindestens eine Epoxydgruppe  enthaltenden organischen Rest bedeuten, und Y für  einen 2wertigen organischen Rest steht, wobei der  Rest Y mindestens eine Epoxydgruppe enthalten  muss, dadurch gekennzeichnet, dass man Acetale der  Formel  
EMI0001.0003     
         worin.    Z' für einen Z entsprechenden Rest steht, der  anstelle der     Gruppen     
EMI0001.0006     
    die Gruppen  
EMI0001.0007     
    bedeutet,

   wobei p     Null    oder     eine    ganze Zahl ist.  
EMI0001.0010     
    enthält, wobei Hal Halogen bedeutet, und Y' für       einen,    Y entsprechenden Rest steht, der anstelle der       Gruppen     
EMI0001.0013     
    die Gruppen  
EMI0001.0014     
    enthält, mit dehydrohalogenierenden Mitteln, behan  delt, und vor oder nach der Dehydrohalogenierung  eiloxydiert.  



       Gemäss    einer bevorzugten     Ausführungsform    des  vorliegenden Verfahrens geht     man    von solchen     Ver-          bindungen    der Formel  
EMI0001.0020     
    aus, worin Z' einen Rest der Formel      Besonders geeignete Ausgangsstoffe für das erfindungsgemässe Verfahren sind Mono-epoxy-acetale  der Formel  
EMI0002.0000     
    worin R1, R2, R3, R4, R", R", R, und R8 Wasser  stoffatome oder niedere Alkylreste mit 1-4 Kohlen  stoffatomen bedeuten, wobei R1 und R5 zusammen  auch eine Alkylengruppe bedeuten können.  



  Ausgangsstoffe,     stellt    man am bequemsten her  durch Anlagerung von Halogenhydrinen des     Glyce-          rins    an die Acetale aus     Cyclohexa-3-en-1,1-di-          methanolen    und Methacrolein, oder vorzugsweise  Crotonaldehyd oder Aerolein, oder durch Anlage  rang von Epihalogenhydrinen an die Anlagerungs  produkte aus diesen Acetalen und     a,w-Alkylen-          glykolen    bzw. an deren Umsetzungsprodukte mit  1,2 Alkylenoxyden.  



  Bei der Epoxydierung können neben den     Di-          epoxyden    infolge Nebenreaktionen gleichzeitig auch  ganz oder nur teilweise hydrolysierte Epoxyde ent  stehen, das heisst     Verbindungen,    bei denen die  Epoxydgruppen des Polyepoxyds der Formel (1) ganz  oder teilweise zu Hydroxylgruppen verseift worden  sind.  



  Es wurde festgestellt, dass die     Anwesenheit    sol  cher Nebenprodukte die technischen Eigenschaften  der gehärteten Polyepoxyde in der Regel günstig be  einflusst. Daher empfiehlt es sich im allgemeinen,  auf eine Isolierung der reinen Polyepoxyde aus dem  Reaktionsgemisch zu verzichten.  



  Die erfindungsgemäss hergestellten epoxydierten  Acetale reagieren mit den üblichen Härtern für  Epoxydverbindungen. Sie lassen sich daher durch Zu  satz solcher     Härter        analog    wie andere     polyfunktionelle     Epoxydverbindungen bzw.

   Epoxydharze vernetzen  bzw.     aushärten.    Als solche     Härter    kommen basische  oder     insbesondere    saure     Verbindungen    in Frage, wie  Amine oder Amide, wie aüphatische und aromatische  primäre, sekundäre und tertiäre Amine,     Mannich-          Basen,    Piperidin; Piperazin, Guanidin und     Guanidin-          derivate,    wie Phenyldiguanidin, Diphenylgaanidin,  Dicyandiamid, Anilinformaldehydharze,     Harnstoff-          Formaldehydharze    und Melamin-Formaldehydharze,  Polymere von Aminostyrolen, Polyamide, z.

   B. solche  aus aliphatischen Polyaminen und di- oder     trimeri-          sierten,    ungesättigten Fettsäuren, Isocyanate,     Iso-          thiocyanate;    mehrwertige Phenole, Chinon, Phenol  aldehydharze, ölmodifizierte Phenolaldehydharze,    Umsetzungsprodukte von Aluminiumalkoholaten bzw.  -phenolaten mit tautomer reagierenden Verbindungen  vom Typ Acetessigester, Friedel-Crafts-Katalysatoren  und deren Komplexe mit     organischen        Verbindungen     und Phosphorsäure.     Bevorzugt    verwendet man als  Härter mehrbasische Carbonsäuren und ihre Anhy  dride, wobei man gegebenenfalls Beschleuniger, wie  tertiäre Amine, mitverwendet.  



  Es wurde gefunden, dass man bei der     Härtung     der genannten Epoxyharze mit     Carbonsäureanhydri-          den    vorteilhaft auf 1 Grammäquivalent     Epoxyd-          gruppen    nur etwa 0,3 bis 0,9 Grammäquivalente  Anhydridgruppen verwendet. Bei Anwendung von  basischen Beschleunigern, wie Alkalialkoholaten oder  Alkalisalzen von Carbonsäuren, können bis 1,0  Grammäquivalente Anhydridgruppen eingesetzt wer  den.  



  Der Ausdruck  Härten , wie er hier     gebraucht          wird,    bedeutet die Umwandlung der     vorstehenden,     Epoxydverbindungen in unlösliche und unschmelz  bare Harze.  



  Die oben genannten     hartbaren    Gemische enthal  ten ausserdem     vorteilhaft    andere     vernetzend    wirkende  Polyhydroxylverbindungen, wie Hexantriol. Selbst  verständlich können den hartbaren     Epoxydverbin-          dungen    auch andere Epoxyde zugesetzt werden, wie  z. B.

   Mono- oder Polyglycidyläther von Mono- oder  Polyalkoholen, wie Butylalkohol, 1,4-Butandiol oder  Glycerin, bzw. von Mono- oder Polyphenolen, wie  Resorcin, Bis - (4 - oxyphenyl) - dimethylmethan oder  Kondensationsprodukte von Aldehyden mit Pheno  len (Novolake), ferner Polyglycidylester von     Poly-          carbonsäuren,    wie Phthalsäure, sowie ferner     Amino-          polyepoxyde,    wie sie z. B. erhalten werden durch  Dehydrohalogenierung von Umsetzungsprodukten  aus Epihalogenhydrinen und primären oder sekun  dären Aminen, wie     n-Butylamin,    Anilin oder     4,4'-          DI-(monomethylamino)-diphenylmethan.     



  Die     hartbaren        Epoxydverbindungen    bzw. deren  Mischungen mit     Härtern    können ferner vor der Här  tung in irgendeiner Phase mit Füllmitteln, Weich  machern,     farbgebenden    Stoffen usw. versetzt werden.  Als Streck- und     Fülhnittel    können beispielsweise  Asphalt,     Bitumen,    Glasfasern,     Glimmer;    Quarzmehl,    
EMI0003.0000     
  
   
EMI0003.0001     
  
       umgesetzten Ausgangsstoffe mehr nachweisbar. Man  erhält so 515 Teile einer viskosen, gelben Flüssig  keit.  



  Das erhaltene Chlorhydrin wird wie folgt     epoxy-          diert:     Man löst die erhaltenen 515 Teile Chlorhydrin;       in    1390     Teilen    Benzol, fügt 20     Teile    wasserfreies  Natriumacetat zu und lässt dann innert 30 Minuten  unter Kühlung bei 35  219 Teile 43,2 % ige Peressig  säure eintropfen. Anschliessend rührt man noch 3.  Stunden nach.

   Darauf     trennt    man die wässerige       Schicht    ab, wäscht und     neutralisiert    die organische  Phase und dampft das Lösungsmittel ab,     analog        wie     im vorangehenden Beispiel beschrieben ist.     Man    er  hält so 486 Teile     einer    gelben viskosen Flüssigkeit    mit einem Epoxydgehalt von 2,63     Epoxydäquiva-          lenten/kg    (92% der Theorie).  



  Das erhaltene Reaktionsprodukt     wird    anschlie  ssend wie folgt dehydrohalogeniert:  479 Teile des erhaltenen epoxydierten Produk  tes werden mit 365 Teilen 30%iger Natronlauge  während 11/2 Stunden bei 50-55      kräftig    verrührt.  Man fügt dann 800 Teile Benzol zu, trennt die  wässerige Schicht ab und     destilliert    das Benzol unter  vermindertem Druck aus der organischen Schicht  ab, wobei man. das Vakuum bis auf 0,1 mm Hg bei  100  Sumpftemperatur steigert.

   Man erhält so  schliesslich 403 Teile eines hellgelben,     dünnflüssigen     Produktes mit einem Epoxydgehalt von 5,5     Epoxyd-          äquivalenten/kg    (86,5 % der Theorie), welches in der  Hauptsache aus dem Diepoxyd der Formel  
EMI0004.0020     
    besteht.

  Process for the production of new acetals containing epoxy groups The subject of the present patent is a process for the production of new acetals of the formula containing at least two epoxy groups
EMI0001.0002
    wherein X1 and X2 are hydrogen atoms or methyl groups and Z is an organic radical containing at least one epoxy group, and Y is a divalent organic radical, where the radical Y must contain at least one epoxy group, characterized in that acetals of the formula
EMI0001.0003
         wherein. Z 'stands for a radical corresponding to Z which replaces the groups
EMI0001.0006
    the groups
EMI0001.0007
    means

   where p is zero or an integer.
EMI0001.0010
    contains, where Hal is halogen, and Y 'stands for a radical corresponding to Y which replaces the groups
EMI0001.0013
    the groups
EMI0001.0014
    contains, treated with dehydrohalogenating agents, and eiloxydiert before or after the dehydrohalogenation.



       According to a preferred embodiment of the present process, such compounds of the formula are used
EMI0001.0020
    where Z 'is a radical of the formula Particularly suitable starting materials for the process according to the invention are mono-epoxy-acetals of the formula
EMI0002.0000
    wherein R1, R2, R3, R4, R ", R", R, and R8 are hydrogen atoms or lower alkyl radicals with 1-4 carbon atoms, where R1 and R5 together can also be an alkylene group.



  Starting materials are most conveniently prepared by adding halohydrins of glycerine to the acetals of cyclohexa-3-ene-1,1-di-methanol and methacrolein, or preferably crotonaldehyde or aerolein, or by adding epihalohydrins to the addition products made from these acetals and a, w-alkylene glycols or their reaction products with 1,2 alkylene oxides.



  In the case of epoxidation, in addition to the di-epoxides as a result of side reactions, completely or only partially hydrolyzed epoxides can be formed at the same time, i.e. compounds in which the epoxy groups of the polyepoxide of the formula (1) have been wholly or partially saponified to hydroxyl groups.



  It was found that the presence of such by-products generally has a favorable influence on the technical properties of the cured polyepoxides. It is therefore generally advisable not to isolate the pure polyepoxides from the reaction mixture.



  The epoxidized acetals produced according to the invention react with the usual hardeners for epoxy compounds. They can therefore be made similar to other polyfunctional epoxy compounds or by adding such hardeners.

   Crosslink or cure epoxy resins. Suitable hardeners are basic or, in particular, acidic compounds, such as amines or amides, such as aüphatic and aromatic primary, secondary and tertiary amines, Mannich bases, piperidine; Piperazine, guanidine and guanidine derivatives, such as phenyldiguanidine, diphenylgaanidine, dicyandiamide, aniline-formaldehyde resins, urea-formaldehyde resins and melamine-formaldehyde resins, polymers of aminostyrenes, polyamides, e.g.

   B. those made from aliphatic polyamines and di- or trimerized, unsaturated fatty acids, isocyanates, isothiocyanates; polyvalent phenols, quinone, phenol aldehyde resins, oil-modified phenol aldehyde resins, reaction products of aluminum alcoholates or phenolates with tautomeric compounds of the acetoacetic ester type, Friedel-Crafts catalysts and their complexes with organic compounds and phosphoric acid. Polybasic carboxylic acids and their anhydrides are preferably used as hardeners, with accelerators such as tertiary amines also being used if appropriate.



  It has been found that when the epoxy resins mentioned are cured with carboxylic acid anhydrides, only about 0.3 to 0.9 gram equivalent of anhydride groups are advantageously used to 1 gram equivalent of epoxy groups. When using basic accelerators, such as alkali alcoholates or alkali salts of carboxylic acids, up to 1.0 gram equivalents of anhydride groups can be used.



  The term hardening as used here means the conversion of the above epoxy compounds into insoluble and infusible resins.



  The abovementioned hardenable mixtures also advantageously contain other crosslinking polyhydroxyl compounds, such as hexanetriol. Of course, other epoxides can also be added to the hardenable epoxy compounds, such as B.

   Mono- or polyglycidyl ethers of mono- or polyalcohols, such as butyl alcohol, 1,4-butanediol or glycerol, or of mono- or polyphenols, such as resorcinol, bis- (4-oxyphenyl) -dimethylmethane or condensation products of aldehydes with phenols (novolaks ), also polyglycidyl esters of polycarboxylic acids, such as phthalic acid, and also amino polyepoxides, as they are, for. B. obtained by dehydrohalogenation of reaction products of epihalohydrins and primary or secondary amines, such as n-butylamine, aniline or 4,4'-DI (monomethylamino) diphenylmethane.



  The hardenable epoxy compounds or their mixtures with hardeners can also be mixed with fillers, plasticizers, coloring substances, etc. in any phase before hardening. As stretching and filling agents, for example, asphalt, bitumen, glass fibers, mica; Quartz flour,
EMI0003.0000
  
   
EMI0003.0001
  
       converted raw materials are more detectable. This gives 515 parts of a viscous, yellow liquid.



  The chlorohydrin obtained is epoxidized as follows: The 515 parts of chlorohydrin obtained are dissolved; in 1390 parts of benzene, 20 parts of anhydrous sodium acetate are added and then 43.2% peracetic acid is added dropwise within 30 minutes with cooling at 35,219 parts. The mixture is then stirred for a further 3 hours.

   The aqueous layer is then separated off, the organic phase is washed and neutralized and the solvent is evaporated off, as described in the preceding example. This gives 486 parts of a yellow viscous liquid with an epoxy content of 2.63 epoxy equivalents / kg (92% of theory).



  The reaction product obtained is then dehydrohalogenated as follows: 479 parts of the epoxidized product obtained are vigorously stirred with 365 parts of 30% strength sodium hydroxide solution for 11/2 hours at 50-55 hours. 800 parts of benzene are then added, the aqueous layer is separated off and the benzene is distilled off from the organic layer under reduced pressure, in the course of which. the vacuum increases to 0.1 mm Hg at 100 sump temperature.

   This finally gives 403 parts of a pale yellow, low viscosity product with an epoxide content of 5.5 epoxide equivalents / kg (86.5% of theory), which is mainly composed of the diepoxide of the formula
EMI0004.0020
    consists.
