Abraham model correlations for describing dissolution of organic solutes and inorganic gases in dimethyl carbonate

ABSTRACT

Experimental solubility data are reported for anthracene, biphenyl, benzil, benzoin, 1-chloroanthraquinone, phenothiazine, pyrene, salicylamide, thioxanthen-9-one, xanthene, benzoic acid, 4-tert-butylbenzoic acid, 4-chloro-3-nitrobenzoic acid, 3,4-dichlorobenzoic acid, 3,4-dimethoxybenzoic acid, 2-hydroxybenzoic acid, 4-methoxybenzoic acid, 2-methylbenzoic acid, 3-methylbenzoic acid, 3-methyl-4-nitrobenzoic acid, 4-nitrobenzoic acid and 3,4,5-trimethoxybenzoic acid dissolved in dimethyl carbonate at 298.15 K. Abraham model correlations are derived for solute transfer into dimethyl carbonate by combining our measured solubility data with published activity coefficient and solubility data retrieved from the published chemical and engineering literature. The derived Abraham model correlations back-calculate the 52 experimental molar solubilities and infinite dilution activity coefficients to within 0.13 log units.
