Solubility of anthracene in ternary 2-butoxyethanol plus alkane plus propanol solvent mixtures

Experimental solubilities are reported for anthracene dissolved in ternary 2-butoxyethanol + cyclohexane + 1-propanol, 2-butoxyethanol + cyclohexane 2-propanol, 2-butoxyethanol + heptane + 1-propanol, and 2-butoxyethanol heptane + 2-propanol solvent mixtures at 298.15 K. Nineteen compositions we re studied for each of the four solvent systems. Results of these measureme nts, along with published anthracene solubility data in 20 additional terna ry two alkane + alcohol and alkane + two alcohol solvent systems, are used to test the predictive ability of the combined nearly ideal multiple solven t (NIMS)/Redlich-Kister and combined NIMS/BAB equations. Computations showe d that the combined NIMS/Redlich-Kister equation predicted the experimental solubility data to within an overall average absolute deviation of about 1 .4% for the 24 systems considered in the present study. A slightly larger d eviation of about 1.6% was noted in the case of the combined NIMS/BAB equat ion.
