Objective To study the catalytic activity of ceric sulfate in the synthesis of butyl acetate. Methods Acetic acid and 1-butanol were reacted to form butyl acetate with ceric sulfate as the catalyst. The investigated factors of the yield included the amount of the catalyst, reaction time, molar ratio of alcohol to acid and repeated uses of the catalyst. Results Experimental results showed that the catalyst was high activity and could be used repeatedly.Under the best condition the yield could reach 84.7%.Conclusion Ceric sulfate is an excellent catalyst in the synthesis of butyl acetate.
