Solubility of anthracene in binary alkane+2-methyl-2-propanol solvent mixtures at 298.2 K

Experimental solubilities are reported for anthracene dissolved in four bin ary alkane + 2-methyl-2-propanol solvent mixtures at 25 degreesC. The alkan e cosolvents studied were n-heptane, cyclohexane, methylcyclohexane and 2,2 ,4-trimethylpentane. Results of these measurements are used to test two mat hematical representations based upon the combined Nearly Ideal Binary Solve nt (NIBS)/Redlich-Kister and Modified Wilson equations. For the four system s studied, the Combined NIBS/Redlich-Kister equation was found to provide t he better mathematical representation of the experimental data, with overal l average absolute deviations between measured and calculated values being approximately +/-0.5%. Slightly larger deviations were noted in the case of the Modified Wilson equation.
