Jiangsu Yimao provides the most advanced methyl acetate production technology based on Reaction Distillation Process by catalytic esterification of acetic acid with methanol. Compared to the traditional sulfuric acid catalyst, what we select is ion exchange resins.
Our methyl acetate production lines have the following features:
1. High conversion yield and high selectivity to methyl acetate is achieved by reactive distillation, and the energy consumption is saved.
2. The methyl acetate product purity can reach in excessive of 99.95%.
3. Catalytic acceleration is induced by solid acid instead of sulfuric acid, which has much lower requirement for the equipment material and thereby reduces the equipment investment.
4. The catalyst has a long service life, i.e., 3 years.
A list of key equipment in our methyl acetate plant is given as below:
