Solubility of anthracene in binary alcohol + dibutyl ether 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 anthracene dissolved in seven binary mixtures containing dibutyl ether with 1-propanol, 2-propanol, 1-butanol, 2-butanol, 1-octanol, 2-methyl-1-propanol, and 3-methyl-1-butanol at 25 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, the combined NIBS/Redlich-Kister provided the better mathematical representations, with deviations between experimental and back-calculated values being on the order of {+-} 1.5% or less in the case of the three-parameter form. Slightly larger deviations were noted for the modified Wilson mathematical representation.
