Description

Verfahren zur Herstellung von Kunstharzen. In dem Patent 339107 ist die Herstellung von Kunstharz beschrieben, welches durch Kondensation von Cyclohexanon oder seinen Derivaten mit Formaldehyd entsteht. Es wurde nun gefunden, daß cyclische Ketone auch mit höheren aliphatischen oder aromatischen Aldehyden unter Bildung von Harzen kondensiert werden können. Man hat schon Methylcyclohexanon mit i bzw. 2 Molen Benzaldehyd unter Verwendung von hiatriumäthylat unter milden Bedingungen kondensiert und dabei wohldefinierte, kristallisierte Verbindungen, nämlich Benzyliden-methylcyclohexanon und Dibenzylidenmethylcyclohexanon erhalten. Es ist daher überraschend, daß man auch bei der Kondensation von Cyclohexanon oder seinen Derivaten mit höheren Aldehyden Kunstharze von vorzüglichen Eigenschaften erhalten kann. 'Man arbeitet zu diesem Zwecke unter so energischen Bedingungen, daß die Kondensation über die anfangs entstehenden niedrig molekularen Reaktionsprodukte hinausgeht.Process for the production of synthetic resins. In the patent 339107 is the production of synthetic resin is described, which is produced by the condensation of cyclohexanone or its derivatives with formaldehyde. It has now been found that cyclic Ketones also formed with higher aliphatic or aromatic aldehydes can be condensed by resins. Methylcyclohexanone with i or 2 moles of benzaldehyde using hiatrium ethylate under mild conditions condensed and well-defined, crystallized compounds, namely benzylidene-methylcyclohexanone and dibenzylidenemethylcyclohexanone. It is therefore surprising that one also in the condensation of cyclohexanone or its derivatives with higher aldehydes Synthetic resins of excellent properties can be obtained. 'You work on this Purposes under such energetic conditions that the condensation over the initially arising low molecular weight reaction products.

Die Kondensation mit den höheren Aldehyden kann mit sauren oder alkalischen Kondensationsmitteln und mit oder ohne Anwendung von Druck vorgenommen werden. Die erhaltenen Harze lösen sich gut in den gebräuchlichen Lösungsmitteln und können in der Lack= und Firnisindustrie Verwendung finden.The condensation with the higher aldehydes can be acidic or alkaline Condensation agents and with or without the application of pressure. the The resins obtained dissolve well in the common solvents and can are used in the paint and varnish industry.

Beispiel i.Example i.

98 Teile Cyclohexanon werden mit 5o Teilen Paraldehyd und io Teilen Ätzkali in einem Schüttelautoklaven iö Stunden lang auf etwa zoo ' erhiizt. Das entstandene Harz wird durch Behandeln mit Dampf und nachheriges Auswaschen und Schmelzen gereinigt. Beispiel 98 Teile Cyclohexanon werden mit iio Teilen Benzaldehyd und io Teilen konzentrierter Salzsäure einige Zeit unter Rühren auf etwa rSo ` erhitzt. Die gelbe Harzmasse erstarrt nach dem Erkalten und kann durch Erhitzen im Vakuum weiter gereinigt werden.98 parts of cyclohexanone are mixed with 50 parts of paraldehyde and 10 parts Caustic potash heated in a shaking autoclave for 10 hours to about zoo '. That The resulting resin is treated with steam and then washed out and melted cleaned. Example 98 parts of cyclohexanone are mixed with iio parts of benzaldehyde and 10 parts of concentrated hydrochloric acid were heated to about 50 ° for some time while stirring. The yellow resin mass solidifies after cooling and can be removed by heating in a vacuum further cleaned.

Beispiel 3.Example 3.

112 Teile Methylcyclohexanon, 22o Teile Benzaldehyd und 5 Teile Ätzlcaii werden im Schüttelautoklaven auf 2c0 bis 220 erhitzt. Das entstandene Harz wird wie im Beispiel i gereinigt.112 parts of methylcyclohexanone, 220 parts of benzaldehyde and 5 parts of caustic soda are heated to 2c0 to 220 in a shaking autoclave. The resulting resin will cleaned as in example i.
