Verfahren zur Herstellung von Alkylketendimeren

The invention relates to a method for producing alkyl ketene dimers by reacting carboxylic acid chlorides with tertiary amines in a molar ratio of between 1: 1 and 1: 1.6 at temperatures of between 65 and 150 DEG C and with a residence time of between 1 and 30 mins in the absence of solvents. Said r...

description	The invention relates to a method for producing alkyl ketene dimers by reacting carboxylic acid chlorides with tertiary amines in a molar ratio of between 1: 1 and 1: 1.6 at temperatures of between 65 and 150 DEG C and with a residence time of between 1 and 30 mins in the absence of solvents. Said reaction partners are intensively mixed and the alkyl ketene dimers are separated from the reaction mixture. Verfahren zur Herstellung von Alkylketendimeren durch Umsetzung von Carbonsäurechloriden mit tertiären Aminen im Molverhältnis 1 : 1 bis 1 : 1,6 bei Temperaturen von 65 bis 150 DEG C und einer Verweilzeit von 1 bis 30 min in Abwesenheit von Lösemitteln unter intensivem Mischen und Abtrennung der Alkylketendimeren.
