Description

Es ist bekannt, Kunstharze durch Kondensation von Aromaten, wie Xylol, mit Formaldehyd herzustellen.It is known that synthetic resins can be produced by condensation of aromatics such as xylene, with formaldehyde.

Es wurde nun gefunden, daß man abwandlungsfähige Kondensate erhält, die sich vorzüglich zur Herstellung von Lacken eignen, wenn man in einem Arbeitsgang Formaldehyd mit Alkylaryläthern, wie insbesondere Phenoläther, und anderen Aromaten ähnlicher Reaktionsgeschwindigkeit, wie reinen aromatischen Kohlenwasserstoffen oder alkylierten aromatischen Kohlenwasserstoffen, kondensiert.It has now been found that modifiable condensates are obtained which are ideally suited for the production of lacquers, if you work in one operation Formaldehyde with alkylaryl ethers, especially phenol ethers, and other aromatics reaction rate similar to that of pure aromatic hydrocarbons or alkylated aromatic hydrocarbons, condensed.

Geeignete Alkylaryläther sind Anisol, Phenetol sowie Substitutionsprodukte derselben, wie alkylierte Alkylaryläther. Die Anwesenheit freier Hydroxylgruppen ist ausgeschlossen, da Phenoläther mit zusätzlich freien Hydroxylgruppen bei der Kondensation mit Formaldehyd in anderer Weise reagieren. Andere Substituenten, wie z. B. Carboxylgruppen, sind unschädlich, so kann die . Phenoxyessigsäure als Ausgangsmaterial dienen. Als aromatische Kohlenwasserstoffe für die Mischkondensation dienen Benzol, Naphthalin, Toluol, Xylol, Trimethylbenzol, Tetramethylbenzol oder Diäthylbenzol. Die harzartigen Mischkondensate sind sehr reaktionsfähig und können zu weiteren wertvollen Kunststoffen modifiziert werden.Suitable alkyl aryl ethers are anisole, phenetole and substitution products same as alkylated alkyl aryl ethers. The presence of free hydroxyl groups is excluded, since phenol ethers with additional free hydroxyl groups in the React condensation with formaldehyde in a different way. Other substituents such as z. B. carboxyl groups are harmless, so the. Phenoxyacetic acid as a starting material to serve. Benzene is used as aromatic hydrocarbons for the co-condensation, Naphthalene, toluene, xylene, trimethylbenzene, tetramethylbenzene or diethylbenzene. The resin-like mixed condensates are very reactive and can lead to further valuable plastics can be modified.

Beispiel 2z6 g Anisol, io6 g m-Xylol, 6oo g einer 3o°/oigen Formaldehydlösung und 51 g Schwefelsäure von 6o° B6 werden unter Rühren 30 Stunden unter Rückfluß erhitzt. Es entsteht ein Kunstharz mit einem Sauerstoffgehalt von i5,7°/0.Example 266 g of anisole, 106 g of m-xylene, 600 g of a 30% formaldehyde solution and 51 g of sulfuric acid at 60 ° B6 are refluxed for 30 hours with stirring. The result is a synthetic resin with an oxygen content of 15.7%.
