SOLUBILITY OF ANTHRACENE IN BINARY ALKANE PLUS METHYL TERT-BUTYL ETHER SOLVENT MIXTURES AT 298.15 K

Experimental solubilities are reported for anthracene dissolved in sev en binary mixtures containing methyl tert-butyl ether (also called 2-m ethoxy-2-methylpropane) with hexane, heptane, octane, cyclohexane, met hylcyclohexane, 2,2,4-trimethylpentane, and tert-butylcyclohexane (als o called (1,1-dimethylethyl)cyclohexane) at 25 degrees C. Results of t hese measurements are used to test two mathematical representations ba sed upon the combined nearly ideal binary solvent (NIBS)/Redlich-Kiste r equation and modified Wilson model. For the seven systems studied, b oth equations were found to provide an accurate mathematical represent ation of the experimental data, with an overall average absolute devia tion between measured and calculated values being on the order of 0.5% .
