在 Ф30填料塔中研究了催化剂随物料流动的催化精馏过程 .对醋酸与正丁醇酯化反应体系 ,考察了催化剂用量、醇酸比、进料流量、进料位置、回流位置等因素对过程的影响 .在选定的实验条件下 ,塔底产品的丁酯含量达 97.83% ,酯对酸的单程转化率达 98.5 2 % . In the Ф30 packed tower catalyst catalysis with the material flow catalytic distillation process for acetic acid and n-butanol esterification reaction system, investigated the catalyst dosage, alkyd ratio, feed flow, feed position, reflux position and other factors Under the selected experimental conditions, the content of butyl ester in the bottom product reached 97.83%, and the single-pass conversion rate of ester to acid reached 98.52%.
