EFFECTS OF LITHIUM ACETATE ON THE MISCIBLITY FOR BENZENE-METHANOL SYSTEM

本文叙述了LiAc·2H_2O对苯-甲醇体系混溶的影响,双液系的混溶温度与盐量成线性关系,可用t=mX_3+t_0表示。外推可得出“t_0曲线”。所得出的上临界溶解温度与临界组成可作为原二元体系无盐时的固有混溶温度曲线。并讨论了所谓的分层能力大小的斜率m和“分层函数R”与浓度及温度的关系。

In the paper, the effects of the salt LiAc · 2H2O on the mutual solubility of Benzene-Methanol system has been dealt with. It is found that the miscible temperature of the two liquid system is proportional tO the concentration of the solt LiAc ·2H2O when the binary liquids mixtrue with a fixed molecular ritio. The relationship of the miscibility temperaure and mole fanction of the solt LiAc ·2H2O Can be expressed as t=mX2+t0 The 't0-Curv' obtained by extrapolation exhibiting upper Critical solubility temperature and critical conposition can be approximately regarded as the intrinsic mutual solubility curve of Benzen-Methanal system with on salts added. The relationship of the slope m. 'Separation Function R' and concentration of the Salt LiAc ·2H2O has been discussed.
