使用三溶剂系统测定有机非电解质的希尔德布兰德溶解度参数。实验希尔德布兰德溶解度参数表示溶质在这三种单独溶剂(乙酸乙酯、1-丙醇和 1,2-丙二醇)中的摩尔分数溶解度的加权平均值。溶剂系统估计溶质的希尔德布兰德溶解度参数在 8.9 至 14.8 (cal/cm3)2(1) 范围内。偏差范围为 0.8% 至 12.9%,极端值最高,中值偏差在 10% 以内。使用五溶剂系统(己烷、乙酸乙酯、1-丙醇、1,2-丙二醇和水)对溶质的希尔德布兰德溶解度参数进行了更广泛的估计,并且精度更高。
A three-solvent system was used to determine the Hildebrand solubility parameters of organic nonelectrolytes. The experimental Hildebrand solubility parameter represents a weighted average of the mole fraction solubilities of the solute in these three individual solvents (ethyl acetate, 1-propanol, and 1,2-propanediol). The solvent system estimated the Hildebrand solubility parameters of solutes within a range from 8.9 to 14.8 (cal/cm3)2(1). Deviations ranged from 0.8 to 12.9%, with the highest value at the extreme and well within 10% at the median. Estimation of the Hildebrand solubility parameters of solutes within a wider range and with somewhat better accuracy was made with a five-solvent system (hexane, ethyl acetate, 1-propanol, 1,2-propanediol, and water).
