摘要 |
FIELD: industrial organic synthesis. ^ SUBSTANCE: process is accomplished via catalytic chlorination of acetic acid at elevated temperature involving as catalyst crude acetyl chloride obtained as by-product in oxyethylidenediphosphonic acid synthesis at acetic acid-to-crude acetyl chloride weight ratio 1:(0.1-0.4). Crude acetyl chloride is employed either individually or in the form of acetic acid solution with content of principal solution no less than 90 wt %. ^ EFFECT: reduced level of dichloroacetic acid in final product and enabled utilization of chemical production waste. ^ 2 cl, 6 ex |
