Solubility of anthracene in multicomponent solvent mixtures containing propanol, butanol, and alkanes

Experimental solubilities are reported for anthracene dissolved in ternary solvent mixtures 1-propanol + 2-propanol + cyclohexane and 1-butanol + 2-bu tanol + cyclohexane, for anthracene dissolved in the heptanary solvent mixt ure l-propanol + 2-propanol + 1-butanol + 2-butanol + cyclohexane + heptane + 2,2,4-trimethylpentane, and for anthracene dissolved in binary solvent h eptane + 2,2,4-trimeyhylpentane at 298.15 K. For the two ternary solvent sy stems anthracene mole fraction solubilities are reported at 19 different te rnary compositions spanning the entire mole fraction range, In the case of heptanary solvent system, solubility data was measured at eight solvent com positions. Results of these measurements are used to test the predictive ab ility of the combined nearly ideal multiple solvent (NIMS)/Redlich-Kister a nd combined NIMS/BAB equations. Computations showed that both solution mode ls provided reasonably accurate predictions for how the mole fraction solub ility varied with solvent compositions; Deviations between predicted and ex perimental values were on the order of +/-0.95% for the better of the two P redictive equations.
