摘要

首次以超重力旋转床（RPB）代替反应精馏塔进行催化反应精馏合成乙酸正丁酯的实验研究，以评估超重力技术在反应精馏领域应用的可行性和优劣性。在本研究中心自主设计的新型RPB中，首次用固体酸催化剂制成旋转床填料置于RPB内腔，填充密度为336kg/m³，乙酸和正丁醇为原料，在RPB中同时进行反应和分离过程。实验中主要考察了旋转床的转子转速对催化精馏效果的影响。结果表明，在转速为700~800r/min时反应的效果最佳，乙酸转化率达88%以上。同时设计催化精馏对比实验，在基本条件相同情况下，催化精馏实验的乙酸转化率为60%，远低于RPB实验，所得产品纯度相差20%以上。因此，超重力条件有利于提高催化剂催化效率。

Abstract

The synthesis of n-butyl acetate has been carried out for the first time in a novel rotating packed bed (RPB) in order to evaluate the feasibility and applicability of high gravity technology in reactive distillation. The n-butyl acetate was synthesized by using a strong acid cation exchange resin as the catalyst and acetic acid and n-butanol as reactants. The catalyst was packed into the RPB with a density of 336kg/m³, and the processes of reaction and distillation were carried out simultaneously. The effect of varying the RPB rotation speed was investigated; the optimal rotation speed was found to be 700-800r/min, giving a conversion of acetic acid of over 88%. When conventional catalytic reactive distillation was carried out with the same proportion of catalyst, the conversion of acetic acid was only 60%, which is significantly worse than in the RPB experiment. The results indicate that high gravity technology can significantly enhance catalyst efficiency in the reactive distillation field.
