Abstract: Dibutyl maleatewas prepared from maleic anhydride and n-butyl alcohol in the presence of p-toluene sulphonic acid. The yield of the ester could reach 95.6% under amount of substance ratio of maleic anhydride, n-butyl alcohol and p-toluene sulphonic acid were 1:4:0. 16, refluxing and water segrating for 70 min.The catalytic activities of p- toluene sulphonic acid, sulfuric acid, Ferric chloride hexahydrate and ammonium ferric sulfate dodecahydrate et al. in synthesis of dibutyl maleate also were comparison.

Key words: dibutyl maleate, synthesis, p- toluene sulphonic acid, catalyst
