The physicochemical indexes and the fatty acid composition of palm kernel oil deodorization distillate were determined so as to make full use of the palm kernel oil deodorization distillate.The optimal methyl esterification conditions of palm kernel oil deodorization distillate were obtained by orthogonal experiment as follows:dosage of methanol 0.8 mL/g, dosage of concentrated sulfuric acid 0.02 mL/g,reaction temperature 65℃,reaction time 120 min.Under these conditions, the esterification rate of palm kernel oil deodorization distillate could reach more than 97%. |
