Abstract : The purpose of the reported research was to study selected examples of three classes of chemical reactions in molecular flow reactors at elevated temperatures. In all cases the gaseous contents of the reactors were determined by mass spectrometric analysis of a molecular beam effusing from a small orifice in the reactor. The reactions were: (1) The thermal decomposition of some symmetric compounds containing metal-metal bonds with the object of producing free radicals by the homolytic fission of the metal-metal bond. The compounds studied were; Co2(CO)8, Mn2(CO)10, Re2(CO)10, (MoCp(CO)3)2 (FeCp(CO)2)2 and (NiCpCO)2. (2) The system, BF3 - B2O3, at high temperatures. (3) The dehalogenation of orthodichlorobenzenes on hot graphite surfaces with the object of producing benzynes. (Author)
