Related Products of 108-47-4, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 108-47-4, 2,4-Dimethylpyridine, introducing its new discovery.
Enthalpies of vaporization and cohesive energies of dimethylpyridines and trimethylpyridines
Molar enthalpies of vaporization for five di- and two tri-methylpyridines were determined with an accuracy of 0.25 per cent, using an adiabatic vaporization calorimeter.The measurements were performed over the temperature range from 313 to 368 K for four dimethylpyridines and from 328 to 368 K for the other compounds.The results were correlated as a function of temperature, and molar enthalpies of vaporization at 298.15 K and the normal boiling temperatures were obtained by extrapolation.Molar cohesive energies were calculated from experimental values for DeltaglHm and correlated as a function of temperature.
