FIELD: chemistry.
SUBSTANCE: invention relates to a method of a liquid-phase chlorination of 1,3-butadiene with obtaining 3,4-dichlorobutene-1 and cis-1,4-dichlorobutene-2 and trans-1,4-dichlorobutene-2 by the interaction of 1,3-butadiene with chlorine. The method is characterised by the fact that as a solvent applied is a reagent - 1,3-butadiene, and a molar ratio 1,3-butadiene : chlorine constitutes 1:1. The process is carried out at a temperature from -5°C to 40°C.
EFFECT: increased output of target products with the reduction of energy consumption and simplification of the technological process.
