Solubility of Anthracene in Ternary 1,4-Dioxane + Alcohol + Cyclohexane Solvent Mixtures at 298.15 K

Abstract

Experimental solubilities are reported for anthracene dissolved in ternary 1,4-dioxane + 1-propanol + cyclohexane, 1,4-dioxane + 2-propanol + cyclohexane, 1,4-dioxane + 1-butanol + cyclohexane, 1,4-dioxane + 2-butanol + cyclohexane, and 1,4-dioxane + 2-methyl-1-propanol + cyclohexane solvent mixtures at 25°C and atmospheric pressure. Nineteen compositions were studied for each of the five solvent systems. Results of these measurements are used to test the predictive ability of the ternary solvent form of the combined NIMS/Redlich-Kister equation. Computations showed that the model predicted the observed mole fraction solubilities to within an overall average absolute deviation of about 4.7%.

“…Molar concentrations were determined by spectrophotometric measurements at 356 nm. Pribyla et al [12][13][14][15][17][18][19][20][21] reported the solubility of anthracene in ternary alkane + 1,1′-oxybisbutane + alcohol, alkane + 2-methoxy-2-methylpropane + alcohol, and alkane + 1,4-dioxane + alcohol solvent mixtures at 298.15 K. Three alkane cosolvents: heptane (a linear alkane), cyclohexane (a cycloalkane), and 2,2,4-trimethylpentane (a highly branched alkane) and five alcohol cosolvents (1-propanol, 2-propanol, 1-butanol, 2-butanol, and 2-methyl-1-propanol) were studied. There has only been a single experimental determination for the solubility of anthracene in each of the ternary solvent systems studied.…”

“…Currently, the most generalised version of the model is referred to as the Jouyban-Acree model [9,10]. To date, Equation (1) has been shown to provide accurate predictions for the solubility of anthracene dissolved in ternary alkane þ alkane þ alcohol [1,2], ternary alkane þ alcohol þ alcohol [3][4][5][6][7][8]11], ternary alkane þ ether þ alcohol [12][13][14][15][16][17][18][19][20], ternary alkoxyalcohol þ alkane þ alcohol [21], ternary alkoxyalcohol þ alcohol þ alcohol [22] and ternary alkoxyalcohol þ alkane þ alkane [23] solvent mixtures. Differences between predicted and observed values were less than 5% for the studied ternary solvent systems.…”
