A process for preparing a cyclic ketone from a cyclic epoxide, comprising the step of: contacting a cyclic epoxide with an alkali or alkaline-earth halide salt in the presence of a polar solvent at a temperature ranging from 120.degree. to 250.degree. C., wherein said cyclic epoxide is unsubstituted or substituted with one or more C.sub.1-5 alkyl or alkenyl groups, and wherein said cyclic epoxide comprises 7-20 ring carbon atoms, and contains up to 5 carbon-carbon multiple bonds.
一种从环状环氧化物制备环状酮的方法,包括以下步骤:在极性溶剂存在下,将环状环氧化物与碱金属或碱土金属卤化物盐接触,在温度范围为120℃至250℃之间,其中所述环状环氧化物未被取代或被取代一个或多个C.sub.1-5烷基或烯基基团,且所述环状环氧化物包含7-20个环碳原子,并且含有高达5个碳-碳多键。
