摘要:

对大豆油脂脱臭馏出物乙酯化工艺进行研究。通过单因素试验分析时间、温度、硫酸质量分数及乙醇与大豆脱臭馏出物质量比对酯化率的影响,并进一步确定乙酯化的最佳工艺条件为大豆脱臭馏出物与乙醇的质量比1.0、硫酸质量分数2%、反应温度80℃、反应时间60min条件下酯化率为90.86%。

Abstract:

The ethyl esterification of soybean oil deodorization distillate (SODD) was optimized using an orthogonal array design. Esterification rate was investigated with respect to time, temperature, sulphuric acid concentration and weight ratio of ethanol to SODD. The optimum conditions for these factors were 60 min, 80 ℃, 2% and 1:1, respectively. Under these conditions, the esterification rate was 90.86%.

Key words: deodorization, distillate, esterification
