Solubility of Anthracene in Binary Alcohol + 2-Methoxyethyl Ether Solvent Mixtures

Abstract

Experimental solubilities are reported for anthracene dissolved in seven binary mixtures containing 2-methoxyethyl ether with 1-propanol, 2-propanol, 1-butanol, 2-butanol, 2-methyl-1-pentanol, 4-methyl-2-pentanol, and 1-octanol at 25°C. Results of these measurements are used to test two mathematical representations based upon the combined nearly ideal binary solvent (NIBS)/Redlich-Kister equation and modified Wilson model. For the seven systems studied, both equations were found to provide an accurate mathematical representation of the experimental data, with an overall average absolute deviation between measured and calculated values being 1.1% and 0.8% for the combined NIBS/Redlich-Kister and modified Wilson equations, respectively.

Solubility of Anthracene in Ternary Propanol + 2,2,4-Trimethylpentane + Cyclohexane and Butanol + 2,2,4-Trimethylpentane + Cyclohexane Solvent Mixtures

“…Karl Fischer titrations performed on select samples both prior to and after equilibration gave, to within experimental uncertainty, identical water contents (mass/mass %) of <0.01%. The methods of sample equilibration and spectrophotometric analysis are discussed in an earlier paper (Powell et al, 1997). Experimental anthracene solubilities in the two propanol + 2,2,4-trimethylpentane + cyclohexane and two butanol + 2,2,4-trimethylpentane + cyclohexane solvent mixtures are listed in Table 1.…”

“…The numerical value of a A (s) used in the modified Wilson computations was a A (s) ) 0.009 84. 17 Each percent deviation is based upon the measured anthracene solubility data at the seven different binary solvent compositions. Careful examination of Table 2 reveals that both equations provided a fairly accurate mathematical representation for how the solubility of anthracene varies with solvent composition.…”
