摘要
报道了α,ω—二元羧酸在不同浓度的N,N—二甲基甲酰胺水溶液中的密度数据和无限稀释表观摩尔体积,并利用了改进的定标粒子理论求解溶质的空腔体积Vc和溶质—溶剂相互作用体积VI,并对VI随碳原子数目和介质浓度的变化情况作了进一步的讨论。
The density of six dicarboxylic acids in aqueous solution of N,N-dimethylformamide at 298,15K were measured. From these data, the apparent molar volumes of dicarboxylic acids at infinite dilution were obtained. The cavity volumes and interaction volumes between solute and solvent were evaluate by modified scaled particle theory. Medium effect and steric effect of solvation had been discussed with the calculated results.
