A MASS SPECTROMETRIC AND THERMODYNAMIC STUDY OF GASEOUS TRANSITION METAL (II) HALIDES,

Abstract

Mass spectrometric and Knudsen effusion techniques were used to study the vaporization of several transition metal (II) halides. The systems studied include FeI2 and the chlorides and bromides of Cr, Mn, Co and N1. The over all temperature range was between 440 and 700 C. For all systems the monomer is the major vapor species in the temperature range studied. Dimeric species were detected in the vapor phase for all systems except Ni Cl2 and NiBr2. Vapor pressure data were combined with mass spectro metric and entropy data to give heats for the dimerization reaction: 2MX2 (g) M2X4 (g). (Author)
