Description

Verfahren zur Herstellung von Kohlensäurederivaten der Glykolmonoaryläther. Die Glykolmonoaryläther liefern bei der Einwirkung von Phosgen Chlorameisensäureester der Formel: R - O - CH. - CH@O - COCI, worin R einen aromatischen Rest bedeutet; durch Einwirkung eines weiteren Moleküls Glykolmonoaryläther, besonders in Gegenwart säurebindender Mittel, gehen diese in die symmetrischen Kohlensäureester: (R - O - CH. - CH@O) 2C0 Über. Läßt man die zunächst gewonnenen Chlorameisensäure ester (Chlorocarbonate) der Glykolmonoaryläther auf beliebige andere Alkohole oder beliebige Chlorameisensäureester auf Glykolmonoaryläther einwirken, so erhält man unsymmetrische Kohlensäureester, welche einen Glykolmonoarylätherrest enthalten.Process for the production of carbonic acid derivatives of glycol monoaryl ethers. The glycol monoaryl ethers produce chloroformic acid esters when exposed to phosgene of the formula: R - O - CH. - CH @ O - COCI, in which R is an aromatic radical; by the action of another molecule of glycol monoaryl ether, especially in the presence acid-binding agents, these go into the symmetrical carbonic acid esters: (R - O - CH. - CH @ O) 2C0 over. Leaving the initially obtained chloroformic acid ester (Chlorocarbonate) the glycol monoaryl ether to any other alcohols or any If chloroformic acid esters act on glycol monoaryl ethers, asymmetrical ones are obtained Carbonic acid esters, which contain a glycol monoaryl ether residue.

Die neuen Kohlensäureester sollen als schwer flüchtige Lösungs- und Weichhaltungsmittel technische Verwendung finden. Vor den zu diesem Zweck bereits verwendeten symmetrischen und gemischten Kohlensäureestern der Phenole haben sie den Vorzug, daß aus ihnen durch Verseifung keine freien Phenole entstehen.The new carbonic acid esters are said to be poorly volatile solvents and Find softeners technical use. Before doing this already They have symmetrical and mixed carbonic acid esters of the phenols used the advantage that no free phenols are formed from them by saponification.

An Stelle der -.,%Tonoaryläther des Äthylenglykols kann man diejenigen des Propylenglykols, des Diäthylenglykols oder von PolyäthvIenglykolen verwenden. Beispiels. In Zoo Gewichtsteile Glykolmonophenyläther «erden unter Rühren 16o Gewichtsteile Phosgen eingeleitet. Die Temperatur steigt von selbst; man hält sie zweckmäßig auf 35 bis 4o0. Nach Beendigung des Einleitens läßt man noch eine Zeitlang rühren, wäscht das Reaktionsgemisch mit Wasser aus und unterwirft es einer fraktionierten Destillation unter vermindertem Druck. Als Hauptfraktion gewinnt man den unter 14. mm Druck bei 1d.20 siedenden Chlorameisensäureester des Glykolmonophenyläthers (etwa 8o Prozent der berechneten Menge), während der Nachlauf die bei 9o0 schmelzenden Kristalle des symmetrischen Kohlensäureesters des Glykolmonophenvläthers enthält. Beispiel e. 3oo Gewichtsteile Glykolmonokresyläther (Gemisch der 31someren) werden in Gegenwart von 12o Gewichtsteilen Calciumcarbonat bei 7o bis 75' mit ioo Gewichtsteilen Phosgen behandelt. Zum Schluß wird eine Zeitlang auf 9o0 erwärmt. Nach dem Auswaschen des Reaktionsproduktes mit Wasser wird der entstandene neutrale Kohlensäureester des Glykolmonokresyläthers unter vermindertem Druck destilliert. Beispiel 3. Durch Einwirkung von Zoo Gewichtsteilen des nach Beispiel 1 dargestellten Chlorameisensäureesters des Glylzolmonophenyläthers auf ioo Gewichtsteile n-Butylalkohol in Gegenwart von 6o Gewichtsteilen Calciumcarbonat und Aufarbeitung des Reaktionsgemisches gemäß Beispiel I und 2 erhält man den gemischten Kohlensäureester des Butanols und Glyleolmonophenyläthers, der andererseits auch aus Chlorameisensäure-n-butylester und Glykolmonophenyläther mit guter Ausbeute entsteht.Instead of the -.,% Tonoaryl ethers of ethylene glycol, those of propylene glycol, diethylene glycol or polyethylene glycols can be used. Example. 160 parts by weight of phosgene are introduced into Zoo parts by weight of glycol monophenyl ether with stirring. The temperature rises by itself; it is expedient to keep it at 35 to 4o0. After the introduction has ended, the mixture is left to stir for a while, the reaction mixture is washed with water and subjected to fractional distillation under reduced pressure. The main fraction obtained is the chloroformic acid ester of glycol monophenyl ether, boiling under 14 mm pressure at 1d.20 (about 80 percent of the calculated amount), while the tail contains the crystals of the symmetrical carbonic acid ester of glycol monophenyl ether, which melt at 90 °. Example e. 300 parts by weight of glycol monocresyl ether (mixture of the 31 isomers) are treated with 100 parts by weight of phosgene in the presence of 120 parts by weight of calcium carbonate at 70 to 75 minutes. Finally, it is heated to 90 for a while. After washing out the reaction product with water, the resulting neutral carbonic acid ester of the glycol monocresyl ether is distilled under reduced pressure. Example 3. By the action of zoo parts by weight of the chloroformic acid ester of glycol monophenyl ether shown in Example 1 on 100 parts by weight of n-butyl alcohol in the presence of 60 parts by weight of calcium carbonate and working up the reaction mixture according to Examples I and 2, the mixed carbonic acid ester of butanol and glycol monophenyl ether, which on the other hand also from chloroformic acid n-butyl ester and glycol monophenyl ether in good yield.
