摘　　要：In the present study,the transesterification of glycerol trioleate was carried out over a basic ionic liquid,1-butyl-3- methylimidazolium hydroxide（[Bmim]OH） and an 87.2%yield of methyl ester was achieved.The product was isolated through simple decantation from the biphasic system due to the immiscibility of[BmimJOH with ester.[Bmim]OH can be easily recovered and reused six times without dramatic decrease in ester yield.In the present study,the transesterification of glycerol trioleate was carried out over a basic ionic liquid,1-butyl-3- methylimidazolium hydroxide（[Bmim]OH） and an 87.2%yield of methyl ester was achieved.The product was isolated through simple decantation from the biphasic system due to the immiscibility of[BmimJOH with ester.[Bmim]OH can be easily recovered and reused six times without dramatic decrease in ester yield.
