Abstract

9842. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. April 25. [Addition. to 61/11.] Ammonia; molybdenum nitride.-The production of ammonia by the process described in the parent Specification is modified by passing nitrogen and hydrogen alternately over heated molybdenum or a nitrogen compound thereof. Increased pressure is preferably used in the process, especially during the passage of the nitrogen, and the temperature is generally kept below 600‹ C. The nitrogen used may contain a small quantity of hydrogen, and other suitable compounds may be added to the molybdenum. In an example, molybdenum nitride, prepared by treating molybdic acid or molybdenum chloride with ammonia, is used. The subjectmatter of Specification 3345/12 is disclaimed.
