新型固体酸SO^2^-~4-MoO3-TiO2催化合成丙酸正丁酯的 研究

制备了新型固体酸SO^2^-~4-MoO3-TiO2，考察了该催化剂在丙酸正丁酯合成反应中的催化活性以及制备条件对催化活性的影响，并与SO^2^-~4-TiO2进行了比较，结果表明，SO^2^-~4-MoO3-TiO2的催化活性明显比SO^2^-~4-TiO2的高，SO^2^-~4和MoO3共存于TiO2上时表现出协同效应。

A study on catalytic performance of a new solid acid SO^2^-~4-MoO3- TiO2 in preparation of n-butyl propanoate

A new solid acid catalyst SO^2^-~4-MoO3-TiO2 was prepared. The activity of the catalyst in esterification of propanoic acid and n- butyl alcohol was measured and compared with that of SO^2^-~4-TiO2. SO^2^-~4-MoO3-TiO2 had better catalytic activity than SO^2^-~4-TiO2. There was evident coordination between SO^2^-~4 and MoO3 when they coexisted on TiO2.
