| Abstract: | When the feed mole ratio of water to methyl acetate reaches 2.0, the ratio of top reflux to feed methyl acetate ranges from 1.8 to 2.53 and the feed space velocity of methyl acetate is 0.442, the conversion of methyl acetate by catalytic distillation technology is as high as 57% and the weight ratio of acetate acid to water in the hydrolysis mixture is higher than 1.3. Compared with the conventional technology, the catalytic distillation technology has a lot of advantages. |
