考虑到间歇蒸馏在化学生产中的长期重要性，令人惊讶的是，操纵操作政策的效用直到20世纪70年代才被理解。这部分是由于寻找时间最优策略的数学困难。Mayur和Jackson的研究也许是对这个问题最优雅和有效的处理方法。Eng。[j] .自然科学进展，1997,22(2):1 - 3。他们使用庞特里亚金的最大原理来寻找理想的多组分混合物分批蒸馏的最佳回流策略。在本文中，受到Mayur和Jackson的经典处理的激励，我们研究了一种新的蒸馏策略和传统的化学反应间歇蒸馏柱配置。这种馏出物策略为一类特殊的等摩尔反应提供了一种新的明确回流策略。对于生产乙酸丁酯的特殊情况，结果表明，这将导致原料的完全转化和高纯度的产品，这是无法实现的。
Considering the longstanding importance of batch distillation in chemical production, it is surprising that the utility of manipulating operating policies was not understood until the 1970s. This is partly due to the mathematical difficulty of finding the time-optimal policy. Perhaps the most elegant and effective treatment of this problem is found in the work of Mayur and Jackson (Chem. Eng. J. 1971, 2, 150−163). They used Pontryagin's maximum principle to find the optimal reflux policy for the batch distillation of ideal multicomponent mixtures. In this paper, motivated by Mayur and Jackson's classic treatment, we examine a novel distillate policy and a conventional column configuration for batch distillation with chemical reaction. This distillate policy leads to a new explicit reflux policy for the special class of equimolar reactions. For the particular case of butyl acetate production, it is shown that this leads to complete conversion of ingredients and high-purity products, which are unattainable ...
