thermodynamic analysis and correlation of Cyromazine in three acetic acid propanoic acid or ethylene glycol water binary solvents at different temperatures
Journal of Molecular Liquids, 2018Co-Authors: Pengshuai Zhang, Rui Zhao, Chi Zhang, Yameng Wan, Baozeng RenAbstract:Abstract The solubility of Cyromazine in three binary solvent mixtures (acetic acid + water, propanoic acid + water, ethylene glycol + water) were measured by a gravimetric method from 278.15 K to 333.15 K under atmospheric pressure. The experimental results reveal that the mole fraction solubility of Cyromazine increased with the increase of temperature in the three solvents. The Apelblat equation, the λh equation, the general single model (GSM) equation and the modified Jouyban-Acree model equation were all applied to correlate the experimental solubility of Cyromazine well. Moreover, the dissolution thermodynamic properties: ΔsolH0 (the apparent standard enthalpy change), ΔsolS0 (the apparent standard entropy change), ΔsolG0 (the apparent standard Gibbs energy change), ζH (relative contribution of enthalpy) and ζTS (relative contribution of entropy) of the dissolution of Cyromazine in the selected solvents were calculated. The positive values of ΔsolH0, ΔsolG0, ζH ≥ 0.5984 and ζTS ≤ 0.4016 indicated that the dissolution of Cyromazine in the three binary solvents was enthalpy-driving and endothermic process. The experimental solubility of Cyromazine in this work can provide good guidance and fundamental data for the crystallization, purification and application of Cyromazine.

Solubility determination and correlation of Cyromazine in sixteen pure solvents and mixing properties of solutions
Fluid Phase Equilibria, 2018Co-Authors: Pengshuai Zhang, Rui Zhao, Chi Zhang, Baozeng RenAbstract:Abstract The solubility of Cyromazine in the pure solvents (methanol, ethanol, 1-propanol, 1-butanol, 1-pentanol, 1-hexanol, 1-heptanol, water, acetone, 2-propanol, isobutanol, 3-methyl-1-butanol and 2-butanol) at 283.15 K–323.15 K, Cyromazine in the pure solvents (acetic acid and acrylic acid) at 293.15 K–333.15 K and Cyromazine in the pure solvent of propanoic acid at 278.15 K–318.15 K. were measured by a laser dynamic method under atmospheric pressure. The experimental results show that the mole fraction solubility of Cyromazine in the sixteen pure solvents decreased according to the following order: acrylic acid > acetic acid > propanoic acid > methanol > ethanol ≈ water > 1-propanol > 1-butanol >1-pentanol >1-hexanol > 1-heptanol > 3-methyl-1-butanol ≈ (2-propanol, 2-butanol, isobutanol and acetone). In order to facilitate industrial application (to improve the purity of Cyromazine by crystallization in industry) and other research studies, the experimental solubility data are correlated with the five thermodynamic models: modified Apelblat equation, λh equation, non-random two liquid (NRTL) model equation, Wilson model equation and van't Hoff equation. Moreover, the mixing Gibbs energy (ΔmixG), mixing entropy (ΔmixS), mixing enthalpy (ΔmixH), activity coefficient ( γ 1 ∞ ) at infinitesimal concentration and reduced excess enthalpy ( H 1 E , ∞ ) were obtained and the mixing process of Cyromazine in the selected solvents are evaluated based on the Wilson model. The relatively close values of γ 1 ∞ and γ1 indicated that the Cyromazine -selected solvents solution systems are not highly non-ideal.
