连续法SO_4^(2-)/TiO_2固体超强酸催化合成乙酸丁酯

Synthesis of n-Butyl Acetate by Using Solid Super Acid catalystSO42-/TiO2 in Continuous Process

以ＳＯ４２－／ＴｉＯ２型固体超强酸为催化剂，采用微型固定床反应器，通过连续法对乙酸和丁酯进行的酯化反应作了研究。找出了反应的最佳条件，即反应温度１００℃，加料速度１０ｍＬ／ｈ。最后在最佳条件下，当醇酸摩尔比为１：１时，反应转化率达９２．０％。

Using SO42-/TiO2 solid super acid as cataylst,the reaction of acetic acid and n-butyl alcohol was studied in fixed bed micro-reactor by continuous process.At last,the best reaction condition was determined,and under this condition,92.0% starting material could be converted into n-butyl acetate.
