Fatty acid ethyl ester of oil - tea camellia seed oil obtained by transesterification was used as a raw material to separate ethyl oleate by molecular distillation(MD). The influences of the main parame- ters of MD on separation process were investigated by orthogonal tests. The results showed that the aver- age content of ethyl oleate in heavy fraction was 88.3%, and the recovery was 64.6% under the condi- tion of distillation temperature 100℃, distillation pressure 10 Pa, feed rate 150 mL/h and wiped film speed 180 r/min. The content of et...
