一种三氟乙酸乙酯的制备工艺

Process Improvement of Ethyl Trifluoroacetate

以三氟乙酸和乙醇为原料,固体超强酸为催化剂直接酯化反应,产物经过精馏提纯后直接在精馏塔顶端收集即可,反应收率在99%以上,产物纯度可达99.9%以上。

Trifluoroacetic acid and ethanol as raw materials, solid superacid as catalyst for the esterifi- cation reaction product directly, after distillation purification directly on the top of the distillation tower can be collected, the yield was above 99%, the purity of the product can reach more than 99.9%.
