摘要
采用硫酸氢钠为催化剂合成乳酸乙酯。研究表明该催化剂具备价廉易得,催化活性高,能有效提高原料利用率,流程简单,操作方便,减少废液排放等优势。产品总收率达88.3%。
Ethyl lactate was synthesized with sodium bisulfate. Experimental results showed that the material usage rate has lincrease and the amount of the waste liquid reduced. It had the simple flow sheet and convenient operation as well. Under the optimum conditions its total yield could reach 88.3% when using the bottm residue and front cut fraction.
