测定了一些单价盐和极性物种在一系列有机溶剂中的部分摩尔体积。溶剂包括乙醇、甲醇、N-甲基甲酰胺(NYF)、碳酸亚丙酯、环丁砜、丙酮、丙酮和4-甲基-2-戊酮。极斑是正丙基溴化物、正丙基氯化物和正丙基氯化物。被检测的单价盐包括L1Br、LiI、LIN03、NaI、KI、RBL、CsBr、四丁基铵、溴化四丁基铵和高氯酸四丁基铵。结果表明，对于单价盐，溶剂对部分摩尔体积的影响最为明显。溶剂对中性溶质的偏摩尔体积影响很小。与Protlc和Protlc溶剂相比，小分子单价盐的溶剂效应最大。结果表明，非离子溶质对溶剂的结构没有明显的影响，而非离子溶质对溶剂的结构有轻微的影响。
The partlal molar volumes of a number of monovalent salts and polar species were measured In a serles of organlc solvents. The solvents Included ethanol, methanol, N-methytformamlde (NYF), propylene carbonate, sulfolane, acetonltrlle, acetone, and 4-methyl-2-pentanone. The polar specles were n -propyl bromlde, n-propyl lodlde, and n-propyl chlorlde. The monovalent salts that were examlned Included LlBr, LII, LIN03, NaI, KI, Rbl, CsBr, tetrabutylammonlum lodlde, tetrabutylammonlum bromlde, and tetrabutylammonlum perchlorate. The malor observatlon was that the solvent effect on the partlal molar volumes was most pronounced for monovalent salts. The solvent effect on the partial molar volume of the neutral solute was very small. The largest solvent effects are seen for the small monovalent salts when comparlng aprotlc and protlc solvents. The conclusion was that the nonionic solutes do not grossly change the structure of the solvent, but the lonlc solutes change the structure of the solvent slgnlflcantly.
