Solubility of anthracene in ternary propanol + butanol + heptane solvent mixtures

Abstract Experimental solubilities are reported for anthracene dissolved in ternary l-propanol+ l-butanol+heptane, l-propanol+2-butanol+heptane, 2-propanol+l-butanol+heptane and 2-propanol+2-butanoI+heptane solvent mixtures at 25°C. Nineteen compositions were studied for each of the four solvent systems. Results of these measurements are used to test the predictive ability of the ternary solvent form of the Combined NIBS/Redlich-Kister equation. Computations showed that the model predicted the observed solubility behavior to within an overall average absolute deviation of about 1.4%.

Solubility of Anthracene in Binary Alkane + 2-Ethoxyethanol Solvent Mixtures at 298.2 K

Abstract Experimental solubilities are reported for anthracene dissolved in six binary alkane + 2-ethoxyethanol solvent mixtures at 25°C. the alkane cosolvents studied were hexane, heptane, octane, cyclohexane, methylcyclohexane and 2,2,4-trimethylpentane. Results of these measurements are used to test two mathematical representations based upon the combined Nearly Ideal Binary Solvent (NIBS)/Redlich-Kister and Modified Wilson equations. for the six systems studied, the combined Nearly Ideal Binary Solvent (NIBS)/Redlich-Kister equation provided the better mathematical representation of the experimental data, with an overall average absolute deviation between measured and calculated values being approximately 0.4%. Slightly larger deviations were noted in the case of the Modified Wilson equation.

Solubility of Trans-Stilbene in Binary Alkane + 1-Propanol Solvent Mixtures at 298.2 K

Abstract Experimental solubilities are reported for trans-stilbene dissolved in six binary alkane + 1-propanol solvent mixtures at 25°C. the alkane cosolvents studied were hexane, heptane, octane, cyclohexane, methylcyclohexane and 2,2,4-trimethylpentane. Results of these measurements are used to test two mathematical representations based upon the combined Nearly Ideal Binary Solvent (NIBS)/Redlich-Kister and Modified Wilson equations. for the six system studied, the combined Nearly Ideal Binary Solvent (NIBS)/Redlich-Kister equation provided the better mathematical representation of the experimental data, with an overall average absolute deviation between measured and calculated values being approximately 0.4%. Slightly larger deviations were noted in the case of the Modified Wilson equation.
