植物油脱臭馏出物甲酯化实验研究

Our country has a rich vegetable oil resources,deodorization distillate is by-products in the process of refining vegetable oil, contains rich free fatty acids, glyceride, stink material, oxidative decomposition product, tocopheryl, and some other listed substances. But at present,the deodorization distillate of content has not got the reasonable comprehensive utilization. This article unifies the related literature, through the experiment methyl, it obtained the best process conditions for mineralization，the methanol and material ratio is 1:1, sodium methoxide and material ratio is 0.02, reaction temperature is 65℃, reaction time is 120 min. In this conditions, the deodorization distillate of esterification rate can reach more than 90%.
