摘要
以WO3 TiO2 SO42 - 固体超强酸为催化剂 ,在釜式反应器内对乙酸和丁醇的液相酯化反应进行了研究。考察了催化剂的活性、选择性、活化能、催化系数、复用性和腐蚀性。在连续分水条件下 ,该催化反应的表观活化能为 42 .9kJ/mol,催化剂的催化系数为 8.12× 10 - 4 。
WO 3?TiO 2?SO 4 2- has been used as a catalyst for the esterification of n butyl alcohol with acetic acid in the liquid phase.The catalytic activity,selectivity,apparent activation energy ( E a ),catalytic coefficient ( k a ),reusability and corrosiveness have been investigated.Under the condition of continuous separation of water, E a is equal to 42.9 kJ/mol,and k a ,8.12×10 -4 .
