From constantboiling mixtures with a minimum, the adsorption of solutes also varies with the composition of mixed solvents, but a negative deviation is observed.
而从具有最低恒沸点的混合溶剂中吸附溶质时,吸附量与溶剂组成的关系与直线呈负偏差。

Benzene, cyclohexane and normal pentane etc. are frequently used as entrainers in industrial production of anhydrous alcohol through constantboiling and fine distillation.
工业生产中常用苯、环己烷、正戊烷等作夹带剂进行恒沸精馏生产无水乙醇。

Production of anhydrous alcohol by constantboiling rectification method has already presented its advantages such as highly-developed mechanization, high yield, high quality and low production costs.
