摘要
本文通过对"共沸"与"恒沸"概念的分析和由来的追踪,指出了目前化工原理教学中"恒沸精馏"的称谓造成了概念混乱的缺陷和弊端,提出了将有共沸物生成的精馏过程一律称为"共沸精馏"的建议。
In this paper the author points out the confusion of the concept by analyzing and tracking the origin of the concept of the ＂azeotrope＂ and ＂azeotropic＂ caused in current teaching of chemical engineering principles about ＂azeotropic distillation＂. Proposals are generated by the process in which immiscible components co-boiling refers to ＂co-distillation＂.
