SOLUBILITY OF ANTHRACENE IN BINARY ALCOHOL PLUS 2-PROPOXYETHANOL SOLVENT MIXTURES

Experimental solubilities are reported for anthracene dissolved in sev en binary mixtures containing 2-propoxyethanol with l-propanol, 2-prop anol, l-butanol, 2-butanol, l-pentanol, l-octanol, and 3-methyl-1-buta nol at 25 degrees C. Results of these measurements are used to test tw o mathematical representations based upon the combined nearly ideal bi nary solvent (NIBS)/Redlich-Kister equation and modified Wilson model. For the seven systems studied, both equations were found to provide a n accurate mathematical representation of the experimental data, with an overall average absolute deviation between measured and calculated values being on the order of 0.5%.
