Abstract

Abstract: The alcoholysis technique of VE acetatewas investigated in this research.Some key technique parameters such as alcohol-ester weight ratio,reaction temperature,reaction time and dosage of catalyst etc were discussed and analyzed.The optimum parameters for the alcoholysis were determined by orthogonal method.Results showed as follows:65 ℃,2 h,alcohol-ester weight ratio 2:1,and 1.1% NaOH(the weight of VE acetate)as catalyst.On these conditions,the alcoholysis rade of VE acetate exceeded 99.7%.

Key words: VE, alcoholysis, VE acetate
