Abstract

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.
