摘　　要：AlCl3改性的H β沸石用于催化正丁酸与正戊醇的酯化反应合成了高产率的丁酸戊酯,测定了该酯化反应的活化能(40.74kJ mol),建立了动力学方程式.并与无催化剂时的活化能及动力学方程式进行了比较.H-β zeolite modified with AlCl3 was used to catalyse the esterification reaction of n-butyric acid with n-pentanol to synthesize amyl butyrate in a high yield. The activation energy (kJ/mol) for the esterification reaction was determined, and its kinetic equation was also established. Both the activation energy and kinetic equation for the esterification reaction were compared with those in the presence of no catalyst, respectively.
