摘要
Experimental solubilities are reported for pyrene dissolved in 11 binary mixtures containing 1-propanol and 2-propanol with 1-butanol, 2-butanol, 2-methyl-1-propanol, 3-methyl-1-butanol, and 1-octanol at 26 degrees 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 systems studied, both equations were found to provide a fairly accurate mathematical representation of the experimental pyrene solubilities, with an average absolute deviation between experimental and back-calculated values of ca. +/-0.5%.
