Abstract:

        The acylation of cyclohexanol with propionic anhydride was studied by using iodine catalyst .The effects of different factors such as reaction time , the mole ratio of cyclohexanol to propionic anhydride , the mass of catalyst on the yield of cyclohexyl propionate were investigated.The results show that the best of reaction conditions are as following :0.1 mole cyclohexanol , the mole ratio of cyclohexanol to pro pionicanhydride is 1.1∶1 and the mass of catalyst is 0 .08 g ram .After reacting 40 minutes under refluxing , the yield of cyclohexyl propionate reaches 92 .2 %.The product is colorless and transparent .The purity of product is 98.7 %.The reaction was repeated five times.It is shown that the catalyst exhibit a good catalytic activity .The advtanges of the reaction are mild conditions, shorter reaction time and easy manipulation .The product was characterized by refractive index and IR.

Key words: Cyclohexyl propionate , Synthesis , Iodine , Catalysis, Acylation

摘要:      以碘为催化剂, 对环己醇与丙酸酐之间的酰化反应进行了研究, 考察了反应时间、酐醇摩尔比、催化剂质量对丙酸环己酯收率的影响。实验结果表明, 当环己醇的物质的量为0 .1 mol, 酐醇摩尔比为1.1∶1 时, 催化剂质量为0.08 g , 回流反应40min 后, 丙酸环己酯收率可达到92 .2 %, 且所得产品无色透明, 纯度为98 .7 %。重复实验5 次表明催化剂具有良好的催化活性。合成反应条件温和, 反应时间较短, 操作简便。同时对产品的折光率和红外光谱进行了表征。
