SOLUBILITY OF ANTHRACENE IN BINARY ALCOHOL PLUS 3-METHOXY-1-BUTANOL SOLVENT MIXTURES

Experimental solubilities are reported for anthracene dissolved in ten binary mixtures containing 3-methoxy-1-butanol with 1-propanol, 2-pro panol, 1-butanol, 2-butanol, 1-pentanol, 2-pentanol, 3-methyl-1-butano l, 4-methyl-2-pentanol, 1-octanol, and 2-ethyl-1-hexanol at 25 degrees C. Results of these measurements are used to test two mathematical re presentations based upon the combined nearly ideal binary solvent (NIB S)/Redlich-Kister equation and modified Wilson model. For the ten syst ems studied, both equations were found to provide an accurate mathemat ical representation of the experimental data, with an overall average absolute deviation between measured and calculated values being 0.4% a nd 0.5% for the combined NIBS/Redlich-Kister and modified Wilson equat ions, respectively.
