| 摘 要： | 以强酸性阳离子交换树脂为催化剂,丁酮、1,2-丙二醇为原料合成了丁酮1,2-丙二醇缩酮,并考察了反应时间、原料配比、催化剂用量、带水剂及用量、催化剂重复使用等因素对反应的影响.通过优化得出较佳工艺条件为：n（丁酮）∶n（1,2-丙二醇）=0.2∶0.26,带水剂环己烷的用量为40 mL,强酸性阳离子交换树脂用量为1.2 g（相对0.2 mol丁酮）,反应时间2 h,此时产物收率为86.29%,w〉98.5%.催化剂不经处理可循环使用多次.

| Abstract: | With strongly acidic cation exchange resin of styrene system used as catalyst,synthesis of butanone 1,2-propanediol ketal was produced by the reaction of 2-butanone and 1,2-propanediol.The effect of reaction time,materials ratio,the content of catalyst,the water-carrying agent and dosage,repetition experiment of catalyst on the synthesis were all studied.Therefore,the favorite technological conditions are presented as following： reaction time is 2 h,n（2-butanone） ∶ n（1,2-propanediol） = 0.2 ∶ 0.26,the water-carring agent（cyclohexane） is 40 mL,the amounts of strongly acidic cation exchange resin is 1.2 g（when 2-butanone is 0.2 mol）.The yield of product is 86.29%,w98.5%.The catalyst can be reused without any treatments. |
