摘要：
The solubilities of ethylbenzene and 1,2-, 1,3-, and 1,4-dimethylbenzene in aqueous sodium chloride solutions having ionic strengths ranging from 0 to 5.00 mol dm-3 have been determined at 298.15 K. The solubilities were determined by headspace analysis using a multiple-injection interrupted-flow (MIIF) technique. The values for the Henry's law constants and aqueous/vapor partition coefficients for the compounds in the solutions studied are also given. Correlations between the measured aqueous solubilities and molar volume, molecular surface areas, and a simple group contribution model are given. Extrapolation of the correlations is used to estimate the aqueous solubilities of the tri- and tetramethylbenzenes, which are liquids at 298.15 K.
