Abstract
Cyclopropane carbonyl chloride is an important intermediate. It was produced by the chemical reaction of γ-butyrolactone as an orginal material, reacted with bis(trichloromethyl)carbonate and isopropanol et al. The new synthetic method used bis(trichloromethyl) carbonate to replace general halogenating agents and included esterification, cyclization, hydrolysis and so on. The product purity was 98.5%.
