ABSTRACT:
A method of producing 2,3-dichlorobutadiene-1,3 comprising dehydrohalogenation of 2,3,4-trichlorobutene-1 with liquid ammonia in the presence of a polymerization inhibitor at a molar ratio of 2,3,4-trichlorobutene-1 to ammonia of 1:1-15 respectively at a temperature selected within the range of from -35.degree. to +20.degree. C under a pressure of 1-8 atm.
The method of the present invention can be performed continuously. The method makes it possible to obviate polymerization of the desired product and formation of undesirable by-products.
