During the low temperature (-20 to 0 deg C) chlorination of α-chlorobutadiene (94-95 deg C conversion) in the presence of tert-butylpyracatechol 1,1-, 1,2- and 1,4-dichloro-1,3-butadienes, 3,4,4- and 1,3,4-trichloro-1-butenes, 1,1,4-trichloro-2-butene, and the products from further chlorination of the 1,1- and 1,2-dichloro-1,3-butadienes (a mixture of 1,1,3,4- and 1,2,3,4-tetrachloro-1-butenes) are formed in ratios 1.6:0.5:21.8:6.5:50.2:13.7:5.7.Variation of the temperature in the investigated range does not have a significant effect on the ratios of the chlorination products.

During the chlorination of chloroprene (80-85percent conversion) in carbon tetrachloride at -5 to 0 deg C in the presence of tert-butylpyrocatechol 1,2-dichloro-1,3-butadiene, 3,3,4-trichloro-1-butene, 2,3,4-trichloro-1-butene, and 1,2,4-trichloro-2-butene are formed in percentage ratios of 20.4:6.7:3.4:69.5.During chlorination to total conversion of chloroprene under these conditions a series of other compounds are also formed as a result of the further chlorination of 1,2-dichloro-1,3-butadiene and 3,3,4-trichloro-1-butene.During the chlorination of 1,2-dichloro-1,3-butadiene to a high degree of conversion 1,2,4-trichloro-1,3-butadiene, 1,2,3,4-tetrachloro-1-butene, and 1,1,2,4-tetrachloro-2-butene are formed in ratios of 11.4:49:39.6.
