Abstract: 1,194,415. Reactions by forming a plasma using a R.F. coupling. UNITED STATES BORAX & CHEMICAL CORP. 17 June, 1968 [3 July, 1967], No. 30545/67. Heading C1A. A high temperature chemical reaction between at least two reactants is effected by passing a gas which may include one of the reactants through a reaction zone in which a plasma of the gas is formed by R.F. coupling, feeding one reactant into the plasma at a point downstream of the centre of the plasma in the direction of gas flow, feeding other reactants into said plasma forming stream or into the formed plasma to form a product and separating the product from the gas stream. The plasma forming gas may be inert to the reactants e.g. Argon. The examples given of the above reaction are (1) Reduction of a boron halide e.g. BCl 3  with hydrogen to give finely divided boron. Preferably argon is used as the plasma forming gas. (2) Reduction of a volatile halide of a metal with hydrogen to give the metal. (3) Reaction between a volatile halide of a metal or non metal with ammonia, carbon perhalide, hydrogen sulphide or a phosphorus halide to give nitride, carbide, sulphide or phosphide respectively, e.g. boron trichloride with ammonia to give boron nitride silicon tetrachloride with ammonia to give silicon nitride. (4) The reaction of a volatile halide of a refractory hard metal with a volatile halide using a hydrogen plasma, e.g. BX 3  + MX # H 2  BM + 4HX where X is a halogen and M is a refractory hard metal e.g. Ti, W, Hf. (5) The reaction of a metal halide with a gas e.g. A/Cl 3  + NH 3 #(A/N) x . The above reactions are the removal of a halogen from a volatile halide. In such a system one reactant is present in or constitutes the plasma forming gas. The above process may also be used for the formation of hydrazine from nitrogen and hydrogen or from ammonia and hydrogen, for the production of hydroxylamine from nitrogen, hydrogen and oxygen, and for the production of hydrogen cyanide from nitrogen and a hydrocarbon.
