Solubility of trans-stilbene in binary alkane+2-butanol solvent mixtures at 298.2

Experimental solubilities are reported for trans-stilbene dissolved in six binary alkane + 2-butanol solvent mixtures at 25 degrees C. The alkane coso lvents studied were hexane, heptane, octane, cyclohexane, methylcyclohexane and 2,2,4-trimethylpentane. Results of these measurements are used to test two mathematical representations based upon the combined Nearly Ideal Bina ry Solvent (NIBS)/Redlich-Kister and Modified Wilson equations. For the six systems studied, the combined Nearly Ideal Binary Solvent (NIBS)/Redlich-K ister equation provided the better mathematical representation of the exper imental data, with an overall average absolute deviation between measured a nd calculated values being approximately 0.5%. Slightly larger deviations w ere noted in the case of the Modified Wilson equation.
