Molecular distillation (MD) was used to increase the purity of octacosanol extracts from transesterified rice bran wax (RBW), and the effects of MD parameters on the purification process and efficiency were studied. The octacosanol content, triacontanol content and the ratio of octacosanol content (C o ) to triacontanol content (C t ) in distillates and residues, the yields of distillates...
The purification of crude octacosanol extract from transesterified rice bran wax was carried out by molecular distillation (MD). A central composite rotate design (CCRD) was used in order to optimize the experimental parameters: distilling temperature and vacuum degree. Through the response surface methodology (RSM), the optimal MD conditions were determined and the quadratic response surfaces were...
