Abstract:

Despite the wide variety of hydride, halide, oxide, oxyhydride, oxyhalide, and other species that can form, there is a scarcity of experimental data available on the rates of reactions of boron compounds. This is especially true for the potentially more interesting compounds wherein the boron atom is formally in a low valence state. The only set of direct kinetic measurements is a recent room-temperature-diffusion flame determination of the rates of oxidation of gaseous boron atoms by some inorganic oxides. Other related information is limited to indirect inferences provided by studies of the reaction of oxygen atoms with diborane and the chemiluminescent reactions of boron atoms. This lack of information is particularly unfortunate because of borons unique position in the periodic table. The chemistry of metal atoms and their compounds, for example, halides, is often quite different from that of the nonmetals, and boron is the lightest element that divides these two regions of the periodic table. This is a report of the first results from our laboratory of a flow-tube study of some reaction rates of boron monofluoride, BF.
