Solubility of pyrene in binary alcohol + 1-propanol and alcohol + 2-propanol solvent mixtures

Solid-liquid equilibrium data of organic nonelectrolyte systems are becoming increasingly important in the petroleum industry, particularly in light of present trends toward heavier feedstocks and known carcinogenicity/mutagenicity of many of the larger polycyclic aromatic compounds. Experimental solubilities are reported for pyrene dissolved in 11 binary mixtures containing 1-propanol and 2-propanol with 1-butanol, 2-butanol, 2-methyl-l-propanol, 3-methyl-l-butanol, and 1-octanol at 26 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%.
