摘　　要：以单质碘为催化剂合成了环戊酮乙二缩酮。当0·10mol环戊酮与0·13mol乙二醇的混合物在50mg碘催化下,以环己烷为溶剂,回流分水40min,产品收率可达66·0%。Cyclopentanone ethylene ketal was synthesized with I_2 as catalyst. The yield of product reached as high as 66.0% when the reaction is undergoing as below: firstly the reaction of a mixture composed of 0.1 mol of cyclopentanone and 0.13 mol of ethanediol was carried out in cyclohexane as solvent in presence of 50 mg I_2 and then the water was separated out by reflux during the period of 40 min.
