densities surface tensions and derived surface thermodynamics properties of Trimethylbenzene propyl acetate or butyl acetate from t 298 15 k to 313 15 k
The Journal of Chemical Thermodynamics, 2007Co-Authors: Yangyi Yang, Jianhong Deng, Hailing Yang, Xiuhuan Zheng, Guanquan Che, Zhongqi HuangAbstract:Abstract Densities (ρ) for binary systems of (1,2,4-Trimethylbenzene, or 1,3,5-Trimethylbenzene + propyl acetate, or butyl acetate) were determined at four temperatures (298.15, 303.15, 308.15, and 313.15) K over the full mole fraction range. The excess molar volumes (VE) calculated from the density data show that the deviations from ideal behaviour in the systems (all being positive, excepting 1,2,4-Trimethylbenzene + butyl acetate system) become more positive with the temperature increasing. Surface tensions (σ) of these binary systems were measured at the same temperatures (298.15, 303.15, 308.15, and 313.15) K by the pendant drop method, the surface tension deviations (δσ) for all system are negative, and decrease with the temperature increasing. The VE and δσ are fitted to the Redlich–Kister polynomial equation. Surface tensions were also used to estimate surface entropy (Sσ) and surface enthalpy (Hσ).

Liquid–liquid equilibria for ternary systems water + acetic acid + 1,2,4-Trimethylbenzene and water + acetic acid + 1,3,5-Trimethylbenzene at (303.2–343.2) K
Fluid Phase Equilibria, 2016Co-Authors: Zhipeng Shen, Qinbo Wang, Linhui Chen, Xiong Zhenhua, Chen ChuxiongAbstract:Abstract Liquid–liquid equilibria (LLE) data for the ternary systems of water + acetic acid + 1,2,4-Trimethylbenzene and water + acetic acid + 1,3,5-Trimethylbenzene were measured under atmospheric pressure at (303.2–343.3) K. The reliability of the experimentally determined tie-line data was verified by comparison with the literature data. Both the nonrandom two-liquid (NRTL) and the universal quasi-chemical activity coefficient (UNIQUAC) models were adopted to correlate the experimental LLE data, and the binary model interaction parameters were obtained. The RMSD values as low as 0.89% and 0.51% were obtained for the two models, respectively, which shows that the experimental LLE data have been successfully correlated by both the NRTL and the UNIQUAC models. The relevant model parameters could be useful for the simulation and optimization of the related separation process. Moreover, the distribution coefficient and separation factor of acetic acid in the two ternary systems were calculated and discussed in detail.
