Kinetics of the elimination reaction of 1, 1, 2, 3-tetrachloropropane had been studied in emulsion system. It was found that the reaction was second order, the major product resulting from the elimination reaction of 1, 1, 2, 3-tetrachloropropane was 1,1,3-trichloropropene-2, the minor products were cis-and traces-1, 2, 3-trichloropro-Igene.
