Study on the Performance and Esterification Activity of Solid Acid Catalysts Containing Fe and Ti

The solid acid catalysts,and havebeen prepared and their esterification activity for n-butanol with acetic acid has been exam-ined,The activity order of them is. It has beenshown by DT and IR that the activity is proportional to the content of adsorbed on thecatalysts and the repeating using catalysts will deactivate from one time to next time due tothe loss of. The analyses by electronic scanning and XRD reveal that the surface textureand crystal phase of the catalysts treated with H_2SO_4 differ from those untreated,which ef-fect the catalytic performance of the catalysts.
