Abstract
PURPOSE: To obtain the titled compound with stable operations over a long time, by dehydrochlorinating 3,4-dichlorobutene-1 in an aquous alkali solution in the pressence of a specific compound such as thiodiphenylamine to suppress the formation of polymers and foaming of a reaction solution.
CONSTITUTION: 3,4-Dichlorobutene-1, and thiodiphenylamine, 2,6-di-t-butyl-p- cresol and sodium sylfide added to an aqueous alkali solution such as an alkali metal hydroxide, and dehydrochlorinated at 70W120°C to give chloroprene. Amounts of thiodiphenylamine, 2,6-di-t-butyl-p-cresol and sodium sulfide added are preferably 0.001W1wt% respectively on the 3,4-dichlorobutene-1, more preferably 0.005W 0.1wt%. The dehydrochlorination reaction may be carried out in the presence of a surface active agent such as potask soap of castor oil as required.
