A Novel Fibrous Zirconium Sulfate Solid Acid Catalyst for Esterification Reaction

The new type of catalytic zirconium sulfate solid acid material was prepared by using collagen fiber as matrices. The catalyst structure remains fibrous confirmed by SEM. Activities of catalyst etherification of acetic acid with n-butanol were evaluated. Optimal esterification conditions are found out. The catalyst was high in catalytic activity for the synthesis of n-butyl acetate, it overcame the drawbacks of liquid acid and it had convenient separation with liquid phase after reaction without corroding equipment, it was easy in recycle, non - polluting. So the catalyst is a promising application.
