trans-Crotonyl chloride Use and Manufacturing

Methods of Manufacturing

Preparation of Raw Materials; 1-1: (Preparation of Crotonic Acid Chloride)First add 1 kg crotonic acid to a 5 L reaction flask, and then add 1650 mL (1.5 mol) thionyl chloride while stirring slowly, a large amount of HCl will be produced. Stir at room temperature until there is no violent emission of gas, and then raise temperature slowly until reflux. Atmospheric distillation is carried out after the reaction is finished, then collect 871 g fraction at 116-124° C., the yield is 72percent.

Uses

Commonly used in the preparation of crotonates and other derivatives
