Description

Verfahren zur Darstellung von öl- und harzartigen Kondensationsprodukten aus aromatischen Kohlenwasserstoffen und Aralkylhalogeniden. Im Hauptpatent 416904 ist ein Verfahren zur Darstellung von Ölen und Harzen beschrieben, welches darin besteht, daß man Aralkylhalogenide bei Abwesenheit von Kondensationsmitteln auf mehrkernige aromatische Kohlenwasserstoffe sowie deren Halogenderivate in der Hitze einwirken läßt.Process for the preparation of oil and resinous condensation products from aromatic hydrocarbons and aralkyl halides. In main patent 416904 a method for the preparation of oils and resins is described which therein consists that aralkyl halides in the absence of condensing agents polynuclear aromatic hydrocarbons and their halogen derivatives in the heat can act.

Es wurde nun gefunden, daß es für den Eintritt der Reaktion vorteilhaft ist, wenn dieser bei Gegenwart von etwas Salzsäuregas vor sich geht.It has now been found that it is advantageous for the reaction to occur is when this happens in the presence of some hydrochloric acid gas.

Beispiel. i 5o Teile Benzylchlorid, in die zuvor in der Kälte 2 Teile trockenes Salzsäuregas eingeleitet wurden, werden mit 5o Teälen Naphthalin in einem Tongefäß erhitzt. Bei 9o° beginnt die Reaktion. Sie verläuft bei 9o bis ioo° unter starker Salzsäureentwicklung. Zur Vervollständigung der Reaktion wird noch i Stunde auf i3o° erhitzt. Das Reaktionsprodukt ist nach dem Abtreiben von unverändertem Ausgangsmaterial durch Wasserdampf ein klares, schwach gefärbtes dickflüssiges Harz.Example. i 5o parts of benzyl chloride, in previously in the cold 2 parts dry hydrochloric acid gas were introduced, are naphthalene in one with 5o Teälene Heated clay pot. The reaction begins at 90 °. It runs below at 90 to 100 degrees strong hydrochloric acid development. Another hour to complete the reaction heated to 130 °. The reaction product is unchanged after the stripping The starting material is a clear, slightly colored, viscous resin by means of steam.
