Solubility of a solute mixture (iodine plus anthracene) in binary and ternary solvent mixtures of xylenes with or without toluene. Comparison with the ideal-like solution model

摘要

Joint solubility measurements have been carried out for a solute mixture (iodine + anthracene) in three binary solvent mixtures (t(B) m-xylene + (1 - t(B)) o-xylene}, (t(B) m- xylene + (1 - t(B)) p-xylene}, and {t(B) o-xylene + (1 - t(B)) p-xylene) and one ternary solvent mixture (t(B) toluene + t(C) m-xylene + (1 - t(B) - t(C)) p-xylene) at the temperature T = 298.15 K, where t(i) denotes mole fraction of solvent i on a solute-free basis. The results are used to test further an ideal-like solution model proposed very recently. The absolute deviation between experimental and theoretical results is not larger than 0.001 for iodine and 0.0002 fur anthracene, respectively, being within the experimental error.
