Abstract
Dibutyl succinate was synthesis from succinic acid and n-butyl alcohol in the presence of P-toluene sulfonic acid. The yield of the ester could reach 97.4% under amount of substance ratio of siccinct acid n-butyl alcohol and P-toluene sulfonic acid were 1∶8∶0.21, refluxed and water segregated for 60 min. The dibutyl maleate, dibutyl adipate and dibutyl sebacate were also synthesis with P-toluene sulfonic acid as catalyst.
