 1751.    KHRIZMAN, I. A., AND KORNIĬCHUK, G. P.  [Role of Iron Nitride in the Catalysis of Ammonia.]  Ber. Inst. Physik. Chem., Akad. Wiss. Ukr. S. S. R., vol. 6, 1936, pp. 95-101; Chem. Abs., vol. 31, 1937, p. 6831.

       NH3 was decomposed catalytically in the interval 250°-470°, the catalyst being the nitride of activated Fe of the type Fe-Al2O3-K2O.  At 410° and higher, a stoichiometric mixture of N2 and H2 was obtained, at 410°-350° the products abounded in N2, and at 350° and lower, the chief product was N2 with traces of H2.  By comparing these results with those obtained when ordinary Fe was used, it becomes evident that the nitride hinders the decomposition of NH3 and that Fe and not the nitride, is the catalyst in the production of NH3.
