正丁烷、正丁烯-1、丁二烯-1, 3在极性非质子溶剂和质子溶砒中的溶剂化
摘要:
本文的目的是研究碳四气体在极性非质子溶剂和质子溶剂中的溶剂化规律。对碳四气体的选择主要考虑不同键型的代表性, 溶剂以极性非质予溶剂为主。
本文用量热法测定了298.15 K、1 atm下正丁烷、正丁烯-1、丁二烯-1,3在二甲基甲酰胺、二甲基亚矾、碳酸丙烯酯、N-甲基吡喀烷酮和甲醇中的摩尔溶解热。依据测定值对碳四气体的溶剂化规律进行了讨论。
用溶度参数法对溶剂化焓进行了理论计算, 在极性非质子溶剂中得到较好的结果, 质子溶剂的有效溶度参数则表现出局限性。
Pierotti理论如不加修正则不能较好地适用于本文体系。

SOLVATION OF n-BUTANE、n-BUTENE-1、BUTADIENE-1,3 IN DIPOLAR APROTIC SOLVENTS AND PROTIC SOLVENT
Abstract:
The molar heats of solution of gaseousn-Butane, n-Butene-1 and Butadiene-1,3 in 4 pure dipolar aprotic solvents (dimethylformamide, dimethy sulfoxide, propylene carbonate and N-methy-2-pyrrolidone) and in a protic solvent(methanol) have been calorimetrically determined at 298.15 K and 1 atm(Table 3).
The calorimetric measurements were made by expansive calorimeter, the sensi- tivity was 0.01 cal. The solute molarities were all below 0.04. The measurements of solute content were made by gas chromatography.
