摘要
Abstract
The esterification process of acidified oil with glycerol was thoroughly investigated by varying reaction temperature, molar ratio of glycerol to the free fatty acids in oil and the monoglyceride content in starting materials.It is found that monoglyceride can significantly promoet hte reaction process and lead to a much lower content of fatty acids in the product.This is elucidated by the additional analysis of experimental liquid-liquid equilibrium data for the binary systems of triglycerides-glycerni,oleic acid-glycerol and monoglyceride-glycerol, as well as the ternary phase diagram of glycerol-monolg yceride-oleic acid system.The comparison betweent he above ternary and bian ryssy tems clearyl indciates that the appearance of monoglyceride remarkably improves the solubility of both glycerol and fatty acids inits counter phase, which can cacount for the observed promotion effect of monoglyceride in hte estre ification process of acidified oli .关键词
