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298.15K、1atm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。
The purpose of this paper is to study the solvatisation of carbon tetrachloride in polar aprotic and protic solvents. The choice of carbon four gas mainly consider the representative of the different key type, the solvent to polar aprotic solvent based. In this paper, the content of n-butane, n-butene-1, butadiene-1,3 in dimethylformamide, dimethylsulfoxide, propylene carbonate, The molar heat of dissolution in the talc and methanol. Based on the measured value of carbon four gas solvation rules were discussed. The enthalpies of solvation are theoretically calculated by the method of solubility parameter, and good results are obtained in polar aprotic solvents. The effective solubility parameters of protic solvents show limitations. Pierotti theory can not be better applied to this system if it is not modified.
