This paper reports studies on synthesis of butyl acetate with solid- supported rare-earthmetal sulphate as catalyst. The solid-supported catalysts are man-made zeolite, active carbon and cation-exchange resin. The best catalyst for synthesis of butyl acetate is found to be the cation-exchange resin supported rare-earth metal sulphate. The yield is 97.2%. The properties of the catalyst is also discussed.
