PROCESS FOR THE CONTINUOUS PRODUCTION OF {60 -CHLOROPROPIONIC ACID

摘要

An improved process for the continuous production of alpha -chloropropionic acid by reaction of propionic acid with chlorine in the presence of halides or acid halides of the elements phosphorus and sulfur at elevated temperature, the improvement consisting in carrying out the reaction in the presence of alpha -chloropropionic acid as solvent and distilling the resultant reaction mixture using the gas formed in the reaction as carrier gas. alpha -chloropropionic acid is used for the production of plant protection agents.
