Solubility of pyrene in binary alkane + 1-octanol solvent mixtures
- Univ of North Texas, Denton, TX (United States). Dept. of Chemistry
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 seven binary mixtures containing 1-octanol with hexane, heptane, octane, cyclohexane, methylcyclohexane, 2,2,4-trimethylpentane, and (1,1-dimethylethyl)cyclohexane 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 system studied, the three-parameter combined NIBS/Redlich-Kister equation was found to provide the better mathematical representation, with deviations between experimental and back-calculated values being on the order of {+-}1.5% or lees. Slightly larger deviations were noted in the case of the two-parameter modified Wilson equation.
