Solubility of Anthracene in Binary Diisopropyl Ether + Alcohol Solvent Mixtures at 298.15 K

Abstract

Experimental solubilities are reported for anthracene in six binary diisopropyl ether + alcohol solvent mixtures at 298.15 K. The alcohol solvents studied were 1-propanol, 1-butanol, 2-propanol, 2-butanol, 2-methyl-1-propanol, and 3-methyl-1-butanol. Results of these measurements were used to test a mathematical representation based on the combined nearly ideal binary solvent (NIBS)/Redlich-Kister equation. For the six systems studied, the combined NIBS/Redlich-Kister equation was found to accurately describe the experimental data, with an average absolute deviation between measured and back-calculated values being approximately ( 0.6 %.

“…Acree and co-workers [51][52][53][54][55] have measured the solubility of anthracene in binary alcohol + 1,4-dioxane, alcohol + 1,1′-oxybisbutane, alcohol + 2-methoxy-2-methylpropane (also called methyl tert-butyl ether), and 1,1′-oxybis[2-methoxyethane] solvent mixtures at 298.2 K. The alcohol solvents included 1-propanol, 2-propanol, 1-butanol, 2-butanol, 2-methyl-1-propanol, 3-methyl-1-butanol, 2-methyl-1-pentanol, 4-methyl-2-pentanol, and 1-octanol. There has only been a single experimental determination for the solubility of anthracene in each of the binary solvent systems studied.…”

“…2 Anthracene, a simple PAH as a model solute, is the subject of a number of solubility studies, and experimental solubility data of anthracene in binary and ternary solvent mixtures have been reported in alcohols, ethers, alkenes, esters, and aromatic compounds by Acree and co-workers. [3][4][5][6][7][8][9] The authors did not study the solubility of anthracene in solvent mixtures containing ketones, nor has the effect of interactions between ketone and alcohol and ester cosolvents been thoroughly investigated in regards to the solubility of a dissolved solute.…”

“…The trained version of the model is capable of predicting unmeasured solubilities in the same solvent systems. The model provided accurate results for solubility data of anthracene in various nonaqueous binary solvents, and there is no need to evaluate its fitness abilities. − , Equation could be extended to calculate the solute solubility in ternary solvent mixtures as ln nobreak.25em C normalm normalS normala normalt = x 1 nobreak.25em ln nobreak.25em C 1 normalS normala normalt + x 2 nobreak.25em ln nobreak.25em C 2 normalS normala normalt + x 3 nobreak.25em ln nobreak.25em C 3 normalS normala normalt + x 1 x 2 ∑ i = 0 2 J i false( x 1 − x 2 false) i + x 1 x 3 ∑ i = 0 2 J i ′ false( …”
