●项目简介:醋酸丁酯是重要的基础有机化工原料,大量用作各过程的溶剂、萃取剂和脱水剂。但国内目前生产过程依然采用传统的硫酸催化酯化—反应后再分离工艺。由于硫酸腐蚀性和氧化性强,设备腐蚀与副反应严重,酯化过程也需在传热性能差的搪瓷反应器中进行,反应和分离都不理想,因而该工艺生产效率低下,不是绿色化的生产。此外,虽然采用固体酸代
● Project Description: Butyl acetate is an important basic organic chemical raw materials, a large number of solvents used for the process, extractant and dehydrating agent. However, the current domestic production process is still using the traditional sulfuric acid esterification - after the reaction and then separation process. Due to the corrosiveness and oxidation of sulfuric acid, equipment corrosion and serious side effects, esterification process also need to heat the poor performance of the enamel reactor, the reaction and separation are not ideal, so the process of production efficiency is low, not green Production. In addition, solid acid substitution is used
