| Abstract: | Synthesis of dibutyl succinate from n-butyl alcohol and succinic acid using a strong acid cation exchange resin as the catalyst was studied. Dibutyl succinate yield of 95.7% was obtained when 0.025 mol succinic acid and 0.2 mol n-butyl alcohol were refluxed to segregate water for 120 min in the presence of 1.5 g strong acid cation exchange resin. The catalyst can be reused for 4 times without remarkable loss of activity. |
