FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention proposes a method for synthesis of 1,2-epoxy-3-chloropropane. Method involves reaction between allyl chloride and hydrogen peroxide in the presence of catalyst comprising zeolite and, possibly, at least one solvent in the epoxidation medium comprising at least one liquid phase. The distinctive feature of the proposed method involves control of pH value of liquid phase and its maintaining at value 1.5 or above but less 4.8. Invention provides enhancing selectivity of the epoxidation reaction resulting to decrease formation of unfavorable by-side products of reaction.
EFFECT: improved method of synthesis.
