Solvent crystallization is the main method used for preparing anthracene and carbazole from the crude anthracene. The key to the optimization of this method is improving the solubility selectivity of the solvent by means of solvent modulating and process optimization. In this study, the solubility of anthracene, phenanthrene, and carbazole in xylene, dimethylformamide (DMF), DMF with amine/amide, isopropanolamine, and chlorobenzene is examined and the solid‐liquid ternary anthracene–carbazole–DMF/(DMF+19.96% isopropanolamine) system phase diagram is determined and applied in the solvent crystallization process. The results showed that the solubility selectivity of xylene increases with increased temperature. Also, selectivity increases with an increase of the amount of isopropanolamine in the mixture of DMF and isopropanolamine, while decreases with increased temperature. Through multiple washings of crude anthracene with xylene, DMF+19.96% isopropanolamine, and chlorobenzene, it was possible to obtain anthracene and carbazole of purity higher than 98 wt %. © 2013 American Institute of Chemical Engineers AIChE J, 60: 275–281, 2014

“…The apparatus and experimental procedure used in this study were those used previously. (11,12) Excess solutes, iodine, and anthracene, and the solvents were placed in amber glass bottles. After shaking in a thermostat controlled at about T = 303 K for 2 d and then in a carefully controlled thermostat at T = (298.15 ± 0.10) K for 6 d, the bottles were placed in the latter thermostat without shaking for 8 h. A pipette, fitted with a sintered-glass filter tip, previously warmed to slightly above T = 298 K, was used to withdraw a sample of the liquid phase.…”

General simple rules have been established both for binary and higher‐order systems related to their pure components and for ternary and higher‐order systems related to their binary subsystems. In this paper we present two new general linear concentration rules, together with their strict thermodynamic aspects and main statistical explanations, for the real systems {A1+A2+…+Aq+B+C+…+Z} related to their subsystems {A1+A2+…+Aq+i} (i∈{B,C,…,Z}) at constant chemical potentials of A1, A2,…,Aq. One of the linear rules holds good for the real system having zero interchange energy among B, C,…,Z, while the other linear rule, for the real system, having nonzero interchange energies among them. In the simplest case of q=1, they are identical with Zdanovskii's rule for mixed electrolyte aqueous solutions, semi‐ideal hydration model for mixed nonelectrolyte aqueous solutions, linear solubility equation for carbon in ternary alloys, and Wang's general linear concentration rules and corresponding solution models for the real systems {A+B+C+…+Z} related to their binary subsystems {A+i} at constant chemical potential of A, respectively, which quantitatively fit the literature experiments for organic and organic‐inorganic mixtures, aqueous and nonaqueous solutions, alloys, molten salt mixtures, slags and nonstoichiometric solid compounds under normal and supercritical conditions. In order to verify their applicabilities at q≥2, isopiestic measurements for fifteen quaternary and quinary aqueous solutions, each containing two unsaturated solutes and one or two saturated solutes, and joint solubility measurements for four quaternary systems, each containing two saturated solutes and two organic solvents, are reported at T=298.15 K. The experimental results are in excellent agreement with the new linear rules.
