Solubility of trans-stilbene in binary alkane+1-propanol solvent mixtures at 298.2 K

Experimental solubilities are reported for trans-stilbene dissolved in six binary alkane + 1-propanol solvent mixtures at 25 degrees C. The alkane cos olvents studied were hexane, heptane, octane, cyclohexane, methylcyclohexan e and 2,2,4-trimethylpentane. Results of these measurements are used to tes t two mathematical representations based upon the combined Nearly Ideal Bin ary Solvent (NIBS)/Redlich-Kister and Modified Wilson equations. For the si x system studied, the combined Nearly Ideal Binary Solvent (NIBS)/ Redlich- Kister equation provided the better mathematical representation of the expe rimental data, with an overall average absolute deviation between measured and calculated values being approximately 0.4%. Slightly larger deviations were noted in the case of the Modified Wilson equation.
