Abstract

PURPOSE: To recover the titled monochloro compound in high yield, by blowing chlorine into liquid diethyl carbonate under the scattered light, etc., chlorinating the diethyl carbonate to a specific conversion, and distilling the reaction mixture.
CONSTITUTION: Chlorine is blown into liquid diethylcarbonate (DEC) under the scattered light or in the presence of an organic peroxide, e.g. benzoyl peroxide, in an amount of 0.1W5wt%, preferably 0.2W2wt%, based on the raw material DEC for the better reaction progress, at 0W100°C for 4W20hr, to chlorinate DEC to 40W90%, conversion thereof, preferably 60W80%, and the resultant reaction mixture is then distilled under the reduced pressure at 100°C or below, to recover the aimed compound. The reaction may be industrially and readily carried out in the dark in the presence of an organic peroxide.
USE: A raw material for a medicine, e.g. synthetic penicillin.
