A novel electric‐arc device, with a torch consuming 100to 240 amps DC has been developed. In previous apparatus of this kind, both reactants passed through the arc together, but now only one component (e.g., hydrogen or nitrogen) is heated in this new‐process. The temperature of this component is raised to a point where it exists in a highly excited state or dissociates into free atoms and then leaves the arc in a stream with supersonic velocity through a hole drilled in the anode, being then mixed with the other reactant. The resultant mixture is then immediately quenched. The design and operation of the torch as well as the mixing and quenching procedures are discussed. The preparation of chlorosilanes, titanium trichloride, titanium nitride, and hydrazine by this method is described.
