| Abstract: | N - butyl lactate was synthesized from lactic acid and n - butyl alcohol in the presence of strongly acidic cationic exchange resin. The yield of the ester can reach 99. 3% under mole ratio of lactic acid and n - butyl alcohol was 0. 1: 0.2, the amount of strongly acidic cationic exchange resin was 0. 5 g, refluxing and water seprating for 100 min. The reusability of the catalyst was studied. |
