Cyclohexanone 1,2propanediol ketal is synthesized from cyclohexanone and 1,2propanediol in the presence of I 2/PAn as catalyst. The factors influencing the yield are discussed and the best conditions are found out by orthogonal test.

• 以碘掺杂聚苯胺为催化剂,对环己酮与1,2-丙二醇为原料合成环己酮1,2-丙二醇缩酮的反应条件进行了正交实验研究,较系统地研究了环己酮与1,2-丙二醇物质的量比、催化剂用量、反应时间等因素对收率的影响。
