Abstract

247,225. Uhde, F. Feb. 9, 1925, [Convention date]. Catalytic agents, preparation of; ammonia, catalytic production of from nitrogen and hydrogen.-Catalysts, for use in the synthesis of ammonia, comprising the reaction product of a ferro- or ferri-cyanide with a salt of a metal of the iron group, are prepared from solutions of the reacting materials in organic solvents free from water; suitable solvents are polyhydric alcohols. In an example, solutions in glycol of ferric chloride and potassium ferricyanide are mixed and the precipitate filtered and dried. The precipitate is prepared for use by treatment with nitrogen and hydrogen at ordinary pressure, and is then used under pressure at a temperature of 350-450‹ C. The Specification as open to inspection under Sect. 91 (3) (a) states that suitable solvents are acetic anhydride and anhydrous formic acid. This subject-matter does not appear in the Specification as accepted.
