Based on the purification and modification of bentonite

titanium-cross-linked Bentonite was prepared with Ning-ming Dentonite as raw material

and the catalytic capability of titanium-cross-linked Bemtpmote in synthesis of n-butyl acetate was also studied. The experiment result shows that titanium-cross-linked Bentonite have the better catalytic capability in the reaction of esterification than that of sulfuric acid at the same conditions.
