摘　　要：在对甲苯磺酸存在下,由乙二酸和正丁酸合成了乙二酸二丁酯,当己二酸、正丁酸和对甲苯磺酸的质量比为1:4:0.2,回流分水30min,该酯收率可达96.6％。Dibutyl adipate was synthesis from adipic acid and n - butyl alcohol in the presence of p - toluene sulphonic acid. The yield of the ester could reach 96.9% under amount of substance ratio of adipic acid, n - butyl alcohol and p - toluene sulphonic acid were 1 :4:0.2, refluxing and water segrating for 30min.
