A spectroscopic method of chemical analysis is used to determine the mole fraction solubilities of 3,5-dimethoxybenzoic acid dissolved in propanenitrile, in eleven additional alkanol solvents (1-pentanol, 1-hexanol, 1-heptanol, 1-octanol, 2-methyl-1-propanol, 2-pentanol, 2-methyl-1-butanol, 3-methyl-1-butanol, 4-methyl-2-pentanol, 2-ethyl-1-hexanol, cyclopentanol) and in three additional alkyl alkanoate solvents (isopropyl acetate, tert-butyl acetate, methyl butyrate) at 298.15 K. Results from our experimental measurements, combined with published partition coefficient and solubility data, are used to calculate the Abraham model solute descriptors of the monomeric form of 3,5-dimethoxybenzoic acid. In total 62 experimental data points were used in the computation. The calculated solute descriptors describe the experimental solubility and partition coefficient data to within an overall standard deviation of 0.064 log units. [ABSTRACT FROM AUTHOR]

Mole fraction solubilities are reported for 1,4-dichloro-2-nitrobenzene dissolved in 24 organic solvents of varying polarity and hydrogen-bonding character. The experimental data are used to calculate Abraham solute descriptors. The calculated solute descriptors describe the experimental data to within an overall average standard deviation of 0.081 log units. Also reported in the manuscript are Abraham model solute descriptors for both 3,4-dichloro-1-nitrobenzene and 2,3-dichloro-1-nitrobenzene based on published literature data. [ABSTRACT FROM AUTHOR]

Experimental solubilities are reported for 3,5-dinitro-2-methylbenzoic acid dissolved in 14 alcohol and 5 alkyl acetate solvents at 298.15 K. The measured solubility data were mathematically correlated with the Abraham solvation parameter model. The solute descriptors that were calculated for 3,5-dinitro-2-methylbenzoic acid describe the experimental molar solubility data to within an overall average standard deviation of 0.081 log units.

The Abraham model is used to calculate the numerical values of the solute descriptors for 2-ethylanthraquinone from experimental solubilities. The correlations are log ( [image omitted] / [image omitted]) = c + e · E + s · S + a · A + b · B + v · V, log ( [image omitted] /CG) = c + e · E + s · S + a · A + b · B + l · L, where [image omitted] and [image omitted] refer to the solute solubility in the organic solvent and water, respectively, CG is a gas phase concentration and E, V, A, B, S and L denote the solute descriptors. The remaining symbols in the above expressions are known solvent coefficients, which have been determined previously for a large number of gas/solvent and water/solvent systems. The Abraham solvation parameter model was found to describe the measured solubility data to within an overall standard deviation of 0.123 log units. [ABSTRACT FROM AUTHOR]

The Abraham solvation parameter model is used to calculate the numerical values of the solute descriptors for 1-chloroanthraquinone from experimental solubilities in organic solvents. The mathematical correlations take the form of where C S and C W refer to the solute solubility in the organic solvent and water, respectively, C G is a gas phase concentration, E is the solute excess molar refraction, V is McGowan volume of the solute, A and B are measures of the solute hydrogen-bond acidity and hydrogen-bond basicity, S denotes the solute dipolarity/polarizability descriptor, and L is the logarithm of the solute gas phase dimensionless Ostwald partition coefficient into hexadecane at 298  K. The remaining symbols in the above expressions are known solvent coefficients, which have been determined previously for a large number of gas/solvent and water/solvent systems. The Abraham solvation parameter model was found to describe the experimental solubility data of 1-chloroanthraquinone to within an overall standard deviation of 0.126 log units.

The Abraham solvation parameter model is used to predict the experimental solubilities of 1,2,4,5-tetramethylbenzene in organic solvents, from the correlation equations, below, and already determined descriptors for 1,2,4,5-tetramethylbenzene. The mathematical correlations take the form of where C s and C w refer to the solute solubility in the organic solvent and water, respectively, C G is a gas phase concentration, E is the solute excess molar refraction, V is McGowan volume of the solute, A and B are measures of the solute hydrogen-bond acidity and hydrogen-bond basicity, S denotes the solute dipolarity/polarizability descriptor, and L is the solute gas phase dimensionless Ostwald partition coefficient into hexadecane at 298  K. The remaining symbols in the above expressions are known solvent coefficients, which have been determined previously for a large number of gas/solvent and water/solvent systems. The Abraham solvation parameter model was found to predict the experimental solubility data of 1,2,4,5-tetramethylbenzene to within an overall standard deviation of 0.15 log units.
