| 摘 要： | 以单质碘为催化剂、通过丁酮和1,2-丙二醇反应合成丁酮1,2-丙二醇缩酮。考察了酮醇物质的量比、催化剂用量以及反应时间对产品收率的影响。结果表明，适宜的工艺条件为：n(丁酮)∶n(1,2-丙二醇)＝1∶1.3，催化剂用量为反应物料总质量的0.3%，带水剂环己烷6 mL，反应时间1.0 h。在此反应条件下，丁酮1,2-丙二醇缩酮收率达70.3%。

| Abstract: | Synthesis of butanone 1,2-propanediol ketal catalyzed by iodine was studied. Influence of butanone/1,2-propanediol molar ratio, catalyst loading and reaction time on the yield of target product was investigated. Optimum condition was obtained as follows: ketone/1,2-propanediol molar ratio = 11.3, catalyst loadings = 0.3% of the mass of reactants reaction time = 1.0 h. Butanone 1,2-propanediol ketal yield of 70.3% was obtained under the optimum condition. |
