SOLUBILITY OF BENZIL IN BINARY ALKANE PLUS METHYL TERT-BUTYL ETHER SOLVENT MIXTURES

Experimental solubilities are reported for benzil (1,2-diphenylethaned ione) dissolved in six binary mixtures containing methyl tert-butyl et her with hexane, heptane, octane, cyclohexane, methylcyclohexane and 2 ,2,4-trimethylpentane at 25 degrees C. Results of these measurements a re used to test two mathematical representations based upon the combin ed nearly ideal binary solvent (NIBS)/Redlich-Kister equation and modi fied Wilson model. For the six systems studied, the combined NIBS/Redl ich-Kister equation was found to provide the more accurate mathematica l representation of the experimental data, with an overall average abs olute deviation between measured and calculated values being on the or der of 0.3%. Slightly larger deviations were noted in the case of the modified Wilson equation.
