Description

Verfahren zur, Darstellung von harzartigen Produkten aus kernmethylierten Phenolen. Durch Patent 355173 ist ein Verfahren zur Darstellung von harzartigen Produkten aus kernmethylierten Phenolen geschützt, welches darin besteht, daß man Kresole, deren Chlorsubstitutionsprodukte oder andere kernmethylierte Phenole bei Temperaturen über ioo° so lange mit Chlor behandelt, bis nur noch wenig mit Wasserdampf flüchtige Bestandteile vorhanden sind und der Rückstand beim Erkalten zu einer amorphen, festen Masse erstarrt. Es wurde nun weiter gefunden, daß man zu ganz ähnlichen Harzen auch gelangt, wenn nvan zunächst das Chlor auf die erwähnten Phenolhomologen bei gewöhnlicher oder wenig erhöhter Temperatur einwirken läßt und die entstandenen kristallisierbaren bzw. öligen kernchlorierten Verbindungen einer nachträglichen Erwärmung auf Temperaturen über Ioo°, gegebenenfalls unter vermindertem Druck, unterwirft.Process for the preparation of resin-like products from nuclear methylated Phenols. By patent 355173 is a method for the preparation of resinous Protected products from nuclear methylated phenols, which consists in that one Cresols, their chlorine substitution products or other nuclear methylated phenols Treated temperatures above 100 ° with chlorine until only a little with water vapor volatile constituents are present and the residue turns into an amorphous, solid mass solidified. It has now been found that very similar resins can be obtained even if the chlorine first contributes to the phenol homologues mentioned normal or slightly elevated temperature can act and the resulting crystallizable or oily nuclear chlorinated compounds of a subsequent Heating to temperatures above 100 °, if appropriate under reduced pressure, is subjected.

Beispiel. 2oo Teile technisch reines Kr esol werden ohne äußere Erwärmaulg so lange chloriert, bis eine Gewichtszunahme von 28o bis 300 Teilen eingetreten ist. Das Reaktionsprodukt wird, zweckmäßig unter verinindertem Druck, auf 16o° erhitzt, wobei Sälzsäure abgespalten wird. Man erhält etwa d.oo Teile eines braunen, harten Hanzes., das in Benzolkohlenwasserstoffen löslich, in Allkohol und verdünnten Alkalien unlöslich ist.Example. 200 parts of technically pure cresol are made without external heating mouth chlorinated until a weight increase of 28o to 300 parts has occurred is. The reaction product is heated to 160 °, expediently under reduced pressure, where salt acid is split off. About d.oo parts of a brown, hard one are obtained Hanzes. Which is soluble in benzene hydrocarbons, in alcohol and dilute alkalis is insoluble.

PATENT-ANspRUcH:. Abänderung des durch Patent 355173 geschützten Verfahrens zur Darstellung von harzartigen Produkten aus kernmethylierten Phenolen, darin bestehend, daß man hier K.resole oder ihre höheren Homologen zunächst bei gewöhnlicher oder wenig erhöhter Temperatur mit Chlor sättig und die Einwirkungsprodukte einer Nacherhitzung auf Temperaturen über ioo°, gegebenenfalls unter vermindertem Druck, unterwirft.PATENT CLAIM :. Modification of the process protected by patent 355173 for the preparation of resin-like products from nuclear methylated phenols, consisting of that here K.resoles or their higher homologues are initially used with ordinary or slightly elevated temperature saturated with chlorine and the action products of post-heating subjected to temperatures above 100 °, optionally under reduced pressure.
