| Abstract: | The catalytic behaviors of cation exchange resin as catalysts on synthesizing n-propyl acetate by reactive distillation were studied.The influence of the reflux ratio,the mole ratio of acid with alcohol and various types of solid acid catalyst for esterification reactions was discussed,and integrating process conditions to screen catalysts.The better processes conditions of reaction was confirmed.The result of experiment indicates that the reflux ratio is 1 ∶2,the mole ratio of acid to alcohol is 1 ∶2,and the yield of n-propyl acetate is 51.49%. |
