Chlorofluorocarbon CFCs, potential alternative HCFCs and HFCs, and related chlorinated compounds: mass spectral study, Part II.
In a previous publication, mass spectrometry was applied to the study of several ions formed by dissociative ionization of ethanes, partially substituted with fluorine and chlorine, and to the determination of the fragmentation pattern of each related compound. The aim of the present investigation was to extend this mass spectral study (70 eV and low ionization energy) to a group of closely related analogs, hydrofluorocarbons (HCFCs), HFCs, chlorinated fluorocarbons, and chlorinated hydrocarbons--halogenated methane, ethane, and propane molecules--to make an attempt to predict the relative bond strength and then the behavior--metabolic pathway and tropospheric degradation--of new HCFCs and HFCs.
