“…Ebulliometric VLE measurements of mixtures containing 2-ethoxyethanol (including the pure components) were performed by Malanowski and coworkers. − , This data is quite consistent with our static measurements. Otherwise, only vapor pressure data with unreasonable trends from the same studies that were excluded in the case of 2-methoxyethanol and single-point data from VLE studies were found in the literature.…”

As a continuation of our effort to establish reliable thermodynamic data for important industrial solvents, dimethoxymethane (CAS RN: 109-87-5), 1,2-dimethoxyethane (CAS RN: 110-71-4), 2-methoxyethanol (CAS RN: 109-86-4), and 2ethoxyethanol (CAS RN: 110-80-5) were studied. Vapor pressure was measured by ebulliometry for dimethoxymethane and by static method for 1,2-dimethoxyethane, 2-methoxyethanol, and 2ethoxyethanol. Heat capacities in the liquid phase of all four compounds were measured by Tian−Calvet calorimetry in the temperature interval (262−358) K. In the case of dimethoxymethane and 1,2-dimethoxyethane, this interval was shortened because of their volatility. The thermodynamic properties in the ideal gaseous state were calculated using the methods of statistical thermodynamics based on calculated fundamental vibrational frequencies and molecular structure data. Calculated ideal-gas heat capacities and experimental data on vapor pressures, liquid phase heat capacities, and vaporization enthalpies were treated simultaneously to obtain a consistent thermodynamic description.Comparisons with literature values are shown for all measured and derived properties. Furthermore, the developed recommended data were used to identify new molecular parameters for the studied solvents within the PC-SAFT (perturbed-chain statistical associating fluid theory) equation of state and to compare their performance with those published in earlier papers; improved performance of the new parameters was achieved.

The saturation pressure of α-methylbenzenemethanol at (293 to 363) K was measured by the static method. The total pressure (P, T, x) was measured by the static method for the system α-methylbenzenemethanol + water at (293.15, 303.15, 313.15, 323.15, 333.15, 343.15, 353.15, and 363.15) K. The system is forming two liquid phases. The solubility was determined with the ampule method. The density inversion temperature was observed in the liquid phases. An azeotrope was found in the system. Below 350 K, it is a positive homoazeotrope, while above this temperature it is a positive heteroazeotrope. The experimental vapor pressures were correlated with the Antoine equation, while VLE was correlated with the NRTL equation.
