Massenspektrometrische Untersuchungen binärer Mischungen aus Alkalimetall- und Erdalkalimetallhalogeniden

Mass Spectrometrical Investigations of Binary Mixtures Alkali Halide – Alkaline Earth Halide The vapor composition of some binary mixtures alkali halide – alkaline earth halide was investigated by high-temperature mass spectrometry. Concentrations of all molecules in gas phase in dependence on the molar composition of liquid mixture were studied. In the vapors over all mixtures exist gaseous heterocomplexes. With increasing radius of the anion a tendency of decreasing stabilities of 1:1 heterocomplexes is stated. The absolute content of gaseous complexes is a function of the ratio of the vapor pressures of the pure components of mixtures. Calculated formation enthalpies fo various stoichiometric heterocomplexes are given.
