文章采用均匀设计法探讨了固体超强酸Ｆｅ２Ｏ３／ＳＯ２－４催化酯化合成氯乙酸乙酯的工作条件。试验设计合理、操作简单、省时省力。酯化工艺“三废”少，得率达８０％以上。
In this paper, the uniform design method was used to investigate the working conditions of the esterification of ethyl chloroacetate catalyzed by solid superacid Fe2O3 / SO2-4. Test design is reasonable, simple operation, saving time and effort. Esterification process “three wastes” less yield rate of 80%.
