Solubility of Phenanthrene in Binary Mixtures of C₁−C₄ Alcohols at 298.2 K

Abstract

Experimental solubilities are reported for phenanthrene in binary solvent mixtures of methanol + 1-propanol, methanol + 1-butanol, ethanol + 1-propanol, ethanol + 1-butanol, and 1-propanol + 1-butanol at 298.2 K. Results of these measurements were used to evaluate the prediction capability of previously developed quantitative structure-property relationships employing the solubility data in monosolvents and the mean deviations (MDs) of the models' predicted values from the measured data varied between (1.7 and 42.5) %. The overall MDs (OMDs) for the prediction methods were 2.8 (( 2.7) % and 14.3 (( 23.3) %, respectively, for water-to-solvent and gas-to-solvent coefficients. Using ab initio prediction methods, the MDs varied between (6.2 and 155.8) %, and the OMDs were 11.4 (( 6.5) % and 92.1 (( 48.0) %.

“…Fakhree et al 78,79 measured the solubility of phenanthrene in binary solvent mixtures containing two alcohol solvents. The solvents included four primary alcohols (methanol, ethanol, 1-propanol, and 1-butanol) and one secondary alcohol (2-propanol).…”

Solubility of Phenanthrene in Ternary Mixtures of C1−C4 Alcohols at 298.2 K

“…Also, solubility amounts in studied monosolvents are in good agreement with previously published data. 6,7 Methanol (0.995 in mass fraction), ethanol (0.999 in mass fraction), 1-propanol (0.995 in mass fraction), and 1-butanol (0.995 in mass fraction) were purchased from Merck. A Karl Fischer titration method showed that the water contents of the solvents were 0.04%, 0.13%, 0.07%, 0.03%, and 0.30%, for methanol, ethanol, 1-propanol, 2-propanol, and 1-butanol, respectively.…”

“…4 It is shown that these models can be applied to obtain calculated solubility data in binary mixtures of solvents with acceptable errors. [4][5][6][7] The J i coefficients are described as…”

“…Its solubility amounts in binary mixture of solvents have been studied. 6,7 To the best of our knowledge, there are no reported solubility data for phenanthrene in ternary solvent mixtures. In this study, solubility of phenanthrene in ternary solvent mixtures consist of ethanol +1-propanol + methanol, ethanol + 1-propanol + 2-propanol, 1-butanol + methanol + 2-propanol, 1-butanol + ethanol + 1-propanol, and 1-butanol + 1-propanol + methanol are reported.…”
