Supported solid-acid catalyst for producing butyl acetic ether

The catalyst used for production of n-butyl acetate contains active component and carrier, in which the active component includes metal sulfate, metal halide and metal oxide, and the carrier includessilica gel, alumino silica gel, molecular sieve, kaolin, diatomite or acid clay, and the weight ratio of active component and carrier is 5-25 : 100, and the active component of the catalyst is supported on the surface of the carrier by adhesive. Said invented load-type solid acid catalyst possesses high activity and selectivity in the esterification reaction for synthesizing n-butyl acetate by using acetic acid and n-butyl alcohol, and the yield of n-butyl acetate can be up to above 98%.
