Abstract
Dibutyl phthalate was sy nthesized from phthalic anhydride and n-butyl alcohol in presence of p-toluene sulphonic acid. The yield of the ester could reach 98% when the mole ratio of p hthalic anhydride ,n-butyl alcohol and p-toluene sulphonic acid was 1∶4∶0. 05,with refluxing and segrating water for 3.0 h.
