| Abstract: | n - Butyl lactate was synthesized from lactic acid and n - butanol in the presence of catalystnanosolid su-peracid SO42-/TiO2. The influence of reaction conditions were investigated and optimal condition was obtained. The results showed that the appropriate conditions should be: weight of catalyst was 1. 5g(weight of lactic acid if 0.1mol ), molar ratio of n - butanol to lactic acid 3. 0:1, reaction time was 2h. The yield of esters was over 86%. |
