Studies on Synthesis of n-Butyl Acetate by Catalysis of Solid Itrastrong Acid TiO_2/SO_4~(2-)

N-Butyl acetate has been synthesized from the basic materials glacier acetic acid and n-butyl alcohol by catalysis of solid ultrastrong acid TiO2/SO42-. The effect of acid-alcohol ratio, acidity of catalyst, amount of catalyst, reaction time, and reaction temperature were investigated. The experimental results showed that when 0.1mol glacier acetic acid was used, the most appropriate conditions were that 0.80g solid ultrastrong acid TiO2/SO42- was used as catalyst, alcohol-acid ratio was 3:1, reaction time was three hours, and reaction temperature was between 120 and 125℃. The yield of the ester was 93.21%, which was a satisfactory result.
