Description
Verfahren zur Herstellung von Lackharzen Es wurde gefunden, daß man zur Lackfabrikation sehr gut geeignete Harze dadurch erhalten kann, daß man reines Dioxydiphenylsulfid oder dessen Homologe mit Harzsäuren durch Erhitzen im Vakuum verestert.Process for the preparation of paint resins It has been found that Resins which are very suitable for paint production can be obtained by using pure resins Dioxydiphenyl sulfide or its homologues with resin acids by heating in a vacuum esterified.
Man hat zwar schon schwefelhaltige Kondensationsprodukte aus Phenolen mit Kolophonium verestert, jedoch nur solche Produkte, welche bereits Harzcharakter zeigen. Reines Dioxydiphenylsulfid ist dagegen ein kristallisierter Körper, welcher bei der Verestexung Harze liefert, die heller sind, höher schmelzen und eine niedrigere Säurezahl besitzen.One already has sulfur-containing condensation products from phenols Esterified with rosin, but only those products that are already resinous demonstrate. Pure dioxydiphenyl sulfide, on the other hand, is a crystallized body, which in the case of esterification, it produces resins which are lighter, have a higher melting point and a lower temperature Have acid number.
Das reine Dioxydiphenylsulfid wird in an sich bekannter Weise durch Einwirkung von rotem Chlorschwefel auf Phenole hergestellt. Die Veresterung mit Harzsäuren, beispielsweise Kolophonium, geschieht im Vakuum je nach Bedarf bei höherer oder niedrigerer Temperatur. Die Anwendung von Vakuum bei der Veresterung von Phenolharzen mit Harzsäuren ist an sich bekannt und gebräuchlich. Der Vorteil der Verwendung von Vakuum bei dem vorliegenden Verfahren wird dadurch erklärt, daß das bei der Veresterung sich abspaltende Wasser unter Vakuum schneller entfernt wird. Es ist infolgedessen auch möglich, die Temperatur etwas zu ermäßigen, was wiederum von Einfluß auf die Helligkeit des fertigen Kunstharzes ist. Zur Veresterung können Kondensationsmittel zugesetzt werden. Das Verhältnis von Naturharz zu dem Dioxydiphenylsulfid kann in manni,gfaltigster Weise geändert werden.The pure Dioxydiphenylsulfid is in a known manner Action of red chlorosulfur produced on phenols. The esterification with Resin acids, such as rosin, occur in a vacuum, depending on the need, at a higher level or lower temperature. The use of vacuum in the esterification of phenolic resins with resin acids is known and used per se. The advantage of using of vacuum in the present process is explained by the fact that the Esterification separating water is removed more quickly under vacuum. It is as a result, it is also possible to reduce the temperature somewhat, which in turn of Influence on the brightness of the finished synthetic resin is. Can be used for esterification Condensing agents are added. The ratio of natural resin to the dioxydiphenyl sulfide can be changed in many different ways.
Beispiel 25 g Dioxydiphenylsulfid, welches aus Phenol und rotem Chlorschwefel erhalten wurde, werden mit t oo g Kolophonium während 6 Stunden im Vakuum (etwa 5 mm Hg) unter Durchleiten eines schwachen Kohlensäurestromes zwecks Verdrängung der Luft allmählich auf 325° erhitzt, wobei die flüchtigen Anteile (etwa 5o%) abdestillieren. Das zurückbleibende Produkt stellt ein gelbbraunes, durchscheinendes, bei gewöhnlicher Temperatur hartes Harz vom Schmelzpunkt von etwa z25° und einer Säurezahl von etwa 20 dar. Es ist löslich in Leinöl und Benzin.Example 25 g of dioxydiphenyl sulfide, which is composed of phenol and red chlorosulfur is obtained, with too g rosin for 6 hours in a vacuum (approx 5 mm Hg) while passing through a weak stream of carbonic acid for the purpose of displacement the air gradually heated to 325 °, the volatile components (about 5o%) distilling off. The remaining product is a yellow-brown, translucent, with ordinary Temperature hard resin with a melting point of about 25 ° and an acid number of about 20. It is soluble in linseed oil and gasoline.
