SOLUBILITY OF ANTHRACENE IN BINARY (2-ALKOXYETHANOL PLUS 2-ALKOXYETHANOL) SOLVENT MIXTURES

Experimental solubilities are reported for anthracene dissolved in bin ary (2-methoxyethanol + 2-ethoxyethanol), (2-methoxyethanol + 2-propox yethanol), (2-butoxyethanol + 2-methoxyethanol), (2-propoxyethanol + 2 -ethoxyethanol), (2-butoxyethanol + 2-ethoxyethanol), and (2-butoxyeth anol + 2-propoxyethanol) solvent mixtures at T = 298.15 K. Results of these measurements are used to test two mathematical representations b ased upon the combined Nearly Ideal Binary Solvent (NIBS)/Redlich-Kist er equation and Modified Wilson model. For the six systems studied, bo th equations were found to provide an accurate mathematical representa tion of the experimental results, with an overall average absolute dev iation between measured and calculated values of the order of 0.3 per cent or less.
