反应蒸馏生产乙酸酯工艺研究进展

Advances in reactive distillation for ester acetate production

反应蒸馏为可逆反应的反应/分离过程设计提供了一个极有吸引力的选择,尤其是对酯化反应和醚化反应。概述了乙酸与C1～C5醇的酯化反应、反应动力学、相平衡,重点介绍了应用反应蒸馏耦合强化过程生产乙酸酯相关的催化剂和工艺流程的改进和开发进展,并对其发展前景作了展望。

Reactive distillation （RD） provides an attractive alternative for reaction/separation processes with reversible reactions, especially for etherification and esterification. The esterifications, reaction kinetics and phase equilibrium of acetic acid with five different alcohols, ranging from C1 to C5 are introduced. Particular emphasis is placed on the catalyst and process development of RD coupling and intensification process for ester acetate production. Finally, the prospect of their development is also discussed.
