Method for producing alkyl ketene dimers |
| abstract |
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 °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. |
