流化催化精馏制备醋酸异戊酯的研究

SYNTHESIS OF ISOAMYL ACETATE USING FLUIDIZING CATALYTIC REACTION RECTIFICATION

在φ３０填料塔中研究了催化剂随物料流动的催化精馏过程。对醋酸与异戊醇酯化反应体系．考查了催化剂用量、进料酸醇比、进料位置、回流比、水相回流位置等因素对过程的影响。在选定的实验条件下，塔顶产品的酯含量达 ９５．１１％。酯对醇的单程转化率超过 ９５％。

In φ30 packing column, the synthesis of isoamyl acetate is studied by using fluidising catalytic reaction rectification, in which the catalyst powder is fluidizing with feed. it has been investigated that catalyst content, acetic acid-alcohol mole ratio, feed positions of acetic acid and isoamyl alcohol, reflux ratio and reflux position of water phase affect on the process. Under the selected experiment conditions, the isoamyl ACetate content of the ether phase at the top of the tower is about 95.11% and th...
