Monte, Manuel J. S. published the artcileThermodynamic Study on the Sublimation of Six Substituted Quinoxalines, Computed Properties of 25983-14-6, the main research area is quinoxaline derivative sublimation thermodn mass spectrometry Knudsen effusion.
The Knudsen mass-loss effusion technique was used to measure the vapor pressures at different temperatures of the following substituted quinoxalines: 2-hydroxyquinoxaline, between 383.17 K and 399.15 K; 2-hydroxy-3-methylquinoxaline, between 375.16 K and 391.15K; 2,3-dichloroquinoxaline, between 313.15 K and 329.15 K; 2,3,6,7-tetrachloroquinoxaline, between 347.16 K and 361.17 K; 2,3-dimethylquinoxaline between 294.14 K and 308.14 K; 2,3-bis(bromomethyl)quinoxaline, between 351.14 K and 365.14 K. From the temperature dependence of the vapor pressure, the standard molar enthalpies of sublimation at the mean temperature of the exptl. range were derived by the Clausius-Clapeyron equation. From these results the standard molar enthalpies, entropies, and Gibbs functions of sublimation at T = 298.15 K were calculated An empirical equation for estimating vapor pressure-temperature data from enthalpies of sublimation values is presented.
Journal of Chemical and Engineering Data published new progress about Clapeyron equation (standard mol.). 25983-14-6 belongs to class quinoxaline, name is 2,3,6,7-Tetrachloroquinoxaline, and the molecular formula is C8H2Cl4N2, Computed Properties of 25983-14-6.
