Description

Verfahren zur Herstellung von Polyglyciden Nach den Angabe * n von N e f (Ann. 335, -231) ist Glycid oder Epihydrinalkohol durch Umsetzung von a-Chlorhydrin mit alkoholischem Kali erhältlich. Derselbe Autor hat, bereits beobachtet, daß Glycid bei längerem Erhitzen in ein -elbliches Harz übergeht, doch konnten erst Levene und Walti (Journ. biol. chemistry 75, 32,5) zeigen, daß in den beim Erhitzen von Glvcid erhältlichen gelben Cr Harzen Poly..lycide vorliegen. In die sen Polv-lyciden sollen die je noch eine freie Hydroxylgruppe tragenden C3-Reste durch Sauerstoffbrücken verbunden sein.A process for preparing Polyglyciden According to the specification * n e N f (Ann. 335, -231) is glycidol or glycidol by reacting a-chlorohydrin available with alcoholic potash. The same author has already observed that glycidol merges with prolonged heating in a -elbliches resin, but could only Levene and Walti (Journ. Biol. Chemistry 75, 32.5), show that in the heat available from Glvcid yellow Cr resins Poly..lycide are present. In these polylycids, the C3 radicals each still bearing a free hydroxyl group are supposed to be linked by oxygen bridges.

Die Gewinnung der Polyglycide aus monoinerem Glycid durch Erhitzen hat, abgesehen von der langen D-auer und der geringen Ausbeute, den Nachteil einer Verunreinigung des Endproduktes mit Acetol bzw. dessen Kondensations- und Zersetzungsprodukten, da Glycid bei höherer Temperatur eine teil--weise Umlagerung in Acetol erfährt.The production of polyglycides from monoinerem glycid by heating has, apart from the long duration and the low yield, the disadvantage of a Contamination of the end product with acetol or its condensation and decomposition products, because glycid undergoes a partial rearrangement in acetol at higher temperatures.

Es wurde gefunden, daß diese Nachteile vermieden und besonders hochpolymere und farblose Polyglycide gewonnen werden können, wenn man die Polymerisation des nionomeren Glycids bei niedriger Temperatur mit Hilfe geeigneter Katalysatoren vornimmt. Als solche haben sich Metallhalogenide, wie z. B. Zinntetrachlorid, Aluminiumchlorid; Alineralsäuren, wie z. B. Schwefelsäure, und Alkalien als brauchbar erwiesen. Mit Hilfe dieser Katalysatoren kann die Polymerisation des Glycids in Lösung und in unverdünntem Zustande, ferner auch bei verschiedenen Temperaturen erfolgen und so der Polymerisationsgrad beeinflußt werden.It has been found that these disadvantages are avoided and are particularly highly polymeric and colorless polyglycides can be obtained by polymerizing the ionomeric glycide at low temperature with the help of suitable catalysts. As such, metal halides, such as. B. tin tetrachloride, aluminum chloride; Alineral acids, such as. B. sulfuric acid, and alkalis have been found useful. With With the help of these catalysts, the polymerization of the glycide in solution and in undiluted state, also take place at different temperatures and so on the degree of polymerization can be influenced.

In seinem Verhalten gegenüber Katalysatoren entspricht demnach das Glycid teilweise dem monomeren Äthylen- und Propylenoxyd, obwohl das Glycid von den genannten monomeren Grundkörpern durch die Gegenwart einer reaktionsfähigen Hydroxylgruppe ausgezeichnet ist.This corresponds to its behavior towards catalysts Glycid partially the monomeric ethylene and propylene oxide, although the glycid of the aforementioned monomeric base bodies by the presence of a reactive Hydroxyl group is excellent.

Das auf die angegebene Weise erhaltene Polyglycid stellt eine sehr zähe, durchsichtige und farblose Masse dar. Sie ist löslich in Wasser, Methylalkohol und Essigsäure. Auf Grund seiner Alkoholnatur läßt sich das Polyglycid wie Cellulose in eine Reihe von Derivaten überführen. Beim Erhitzen mit Essigsäureanhydrid und Natriumacetat erhält man beispielsweise das Acetat, unlöslich in H,0, löslich in Aceton und Benzol, ferner in Benzolalkohol, mit Formaldehyd wird ein durcbsichtig klares, wasserunlösliches Kondensationsprodukt gewonnen.The polyglycide obtained in the manner indicated is a very good one tough, transparent and colorless mass. It is soluble in water, methyl alcohol and acetic acid. Due to its alcoholic nature, the polyglycide can be used like cellulose converted into a number of derivatives. When heated with acetic anhydride and Sodium acetate, for example, gives the acetate, insoluble in H, O, soluble in Acetone and benzene, also in benzene alcohol, with formaldehyde become transparent clear, water-insoluble condensation product obtained.

Es wurde weiterhin gefunden, daß die- auf die beschriebeneWeise erhaltenen Polyglycide bzw. ihre Derivate in besonderem Maße für die Herstellung von Lacken, plastischen Massen, Formstücken u. dgl. geeignet sind. Die erwähnten Polymerisate können sowohl für sich als auch im Gemisch mitWeichmachungsmitteln, Füllstoffen oder anderen Bindemitteln, z. B. Cellulosederivaten oder künstlichen Harzen, verwendet werden. Die glasklare Beschaffenheit der nach dem angegebenen Verfahren erhaltenen Polyglycide gestattet ferner ihre Verwendung als Zwischenschicht für die Herstellung von nicht splitterndem Glas.It has also been found that these are obtained in the manner described Polyglycides and their derivatives, especially for the production of paints, Plastic masses, fittings and the like are suitable. The polymers mentioned can be used both on their own and in admixture with plasticizers and fillers or other binders, e.g. B. cellulose derivatives or synthetic resins are used will. The crystal clear nature of the obtained by the specified procedure Polyglycides permitted also their use as an intermediate layer for the production of non-splintering glass.

Aus f ü h r u n g s b e i s p i e 1 ioo g monorneres Glycid werden bei -.25' unter intensivem Rühren tropfenweise mit o,6 g Zinntetrachlorid versetzt. Nach mehrtägigem Aufbewahren im Kühlschrank ist ein farbloses, zähes, kaum bewegliches Harz efitstanden. Durch Aufkochen der wässerigen Lösung kann das. Zinn als Hydrat abgeschieden werden. Aus der filtrierten Lösung ist das Polyglycid durch Eindampfen erhältlich.From f ü hrun g s b ice p y 1 ioo g monorneres glycidol are at -.25 'with vigorous stirring dropwise with o, added 6 g of tin tetrachloride. After several days of storage in the refrigerator, a colorless, viscous, barely mobile resin has emerged. The tin can be deposited as a hydrate by boiling the aqueous solution. The polyglycide can be obtained from the filtered solution by evaporation.
