摘　　要：通过改变甲醇用量、温度、时间、催化剂用量等各种条件对脂肪酸甲酯化过程进行控制。研究 表明:脱臭馏出物脂肪酸甲酯化适宜条件为:溶剂:原料(V／w)=1.1:1;甲酯化时间:2小时;甲酯化 温度:60℃;催化剂:原料(V／W)=0.01:1,在该条件下,脂肪酸甲酯化率达到98％。Esterification process of soybean oil deodorizer distillate is mentioned in .this thesis, Ester-ification rate can be controlled by altering solvent-to-material ratio, esterification time, esterification temperature, catalyst-to-material ratio, and other conditions. Results suggest that the optimum esterification conditions are as follows: solvent:material (V/W)= 1.1:1, esterification time is 2 hours, temperature is 60℃, catalyst:material (V/W) = 0.01:1. under this condition the esterification rate is 98%.
