Verfahren zur Herstellung von Estern natürlicher oder künstlicher Harzsätiren.
EMI1.1
bisher nur die Ester gewonnen, die aus Kolophonium oder Kopalen mit Hilfe von Glykol oder Glycerin dargestellt wurden. Während die Veresterung der Harzsäuren des Kolophoniums ohne Schwierigkeiten vor sieh geht, traten bei der Veresterung der Kopalsäuren häufig sehr störende Gelatinierungen auf. Es ist zwar gelungen, durch Anwendung ganz bestimmter Verfahren diese Gelatinierungsgefahr mehr

Es wurde nun gefunden. dass man alle Arten Harzsäuren, insbesondere aber die sonst schwer zu veresternden Harzsäuren, wie z. B. die des Kongokopals, in der einfachsten Weise in Ester überführen kann, wenn man sie mit Glykolderivaten verestert. die aus Glykol durch teilweise Veresterung oder

Glykolderivat auf Temperaturen über 180 bei gewöhnlichem, erhöhtem oder vermindertem Druck.
Die Reaktion kann in bekannter Weise durch Zugabe von Katalysatoren, wie Metalloxyden, wasserentziehenden Säuren und Salzen usw.. beschleunigt werden. Die Veresterung kann entweder unter Rückflusskühlung oder unter gleichzeitigem Abdestillieren des entstellenden Wassers ausgeführt werden.

Die nach vorliegendem Verfahren hergestellten Ester zeichnen sich durch besondere Wetterfestigkeit und gute Löslichkeit aus.

aus Phenol : Aceton und Formaldehyd in folgender Weise hergestellt :
1250 g Phenol und 260 g Aceton werden unter Zugabe von 125 y konzentrierter Salzsäure 24 Stunden bei Temperaturen bis zu 80 stehengelassen. Die abgeschiedenen Kristalle werden abgesaugt, getrocknet und gereinigt ; Ausbeute 826 g.

Das so erhaltene 4. 4'-Dioxydiphenyldimethylmethan wird in der äquimolekularen Menge 1%iger wässeriger Natronlauge gelöst, nach Zusatz von 4 Mol 30%iger wässeriger Formaldehydlösung 24 bis

Der Ester löst sich in Alkohol bis 1: 4, in Butylalkohol bei beliebiger Verdünnung klar, während ein gleichartig mit Glycerin hergestellter Ester in beiden Lösungsmitteln so gut wie unlöslich ist.

Process for the production of esters of natural or artificial resin sutures.
EMI1.1
so far only the esters obtained from rosin or copals with the help of glycol or glycerine. While the esterification of the resin acids of the rosin proceeds without difficulty, very troublesome gelatinization often occurred during the esterification of the copal acids. It has been possible to reduce this risk of gelatinization by using very specific procedures

can.
It has now been found. that all types of resin acids, but especially the otherwise difficult to esterify resin acids, such as. B. that of the Congo chopal, can be converted into esters in the simplest way if they are esterified with glycol derivatives. those made from glycol by partial esterification or

Glycol derivative at temperatures above 180 at ordinary, elevated or reduced pressure.
The reaction can be accelerated in a known manner by adding catalysts such as metal oxides, dehydrating acids and salts, etc. The esterification can be carried out either with reflux cooling or with simultaneous distilling off of the disfiguring water.

such, come in particular the glycol monoesters. such as B. Glykolmonoaeetat, Glykolmonobenzoat. monoleinoleic acid glycol, monoabietic acid glycol and the like a., which all boil sufficiently high. into consideration.
The esters produced by the present process are distinguished by their particular weather resistance and good solubility.

1250 g of phenol and 260 g of acetone are left to stand at temperatures of up to 80 for 24 hours with the addition of 125 g of concentrated hydrochloric acid. The deposited crystals are filtered off, dried and cleaned; Yield 826g.

The ester dissolves in alcohol up to 1: 4, in butyl alcohol it is clear at any dilution, while an ester prepared in the same way with glycerine is practically insoluble in both solvents. The ester obtained is
