Publication number: 20080199386Abstract: Ammonium hexachlororuthenate is produced by adding ammonium chloride to a hydrochloric acid solution containing ruthenium. The ammonium hexachlororuthenate is baked to obtain the ruthenium powder. When the moisture content of the ammonium hexachlororuthenate is high, the baked product is so hard sintered product that its pulverization is not easy. In accordance with the present invention, the following steps are carried out. Hydrochloric acid solution containing ruthenium is held at a temperature of 80 to 95° C. for three hours or longer. The ammonium chloride is then added to the hydrochloric acid solution which is stirred by a stirring mill at the rotation of 200 revolutions per minute or more. The hydrochloric acid solution is held at a temperature of from 85 to 95° C. for 1 hour while being stirred at 200 rpm. The resultant precipitate of ammonium hexachlororuthenate is filtered. The inventive crystals of precipitated ammonium hexachlororuthenate has 10 mass % or less of moisture content.Type: ApplicationFiled: January 28, 2008Publication date: August 21, 2008Applicant: NIPPON MINING & METALS CO., LTD.Inventors: Hifumi Nagai, Yuji Kawano

The tetraperchlorate formed is useful as the oxidizer component of solid rocket propellants, pyrotechnic compositions and gas generators.Type: GrantFiled: September 30, 1975Date of Patent: October 11, 1977Assignee: Thiokol CorporationInventor: Theodore C. Crawford

Patent number: 4038372Abstract: Chloramine is continuously manufactured on a large scale by reacting gase chlorine with gaseous ammonia. Recovery of the chloramine is then effected by purging the area adjacent to the reactor discharge zone with either an inert gas or ammonia, and entraining the product steam in a high velocity jet of a cooling gas.Type: GrantFiled: May 5, 1976Date of Patent: July 26, 1977Assignee: The United States of America as represented by the Secretary of the NavyInventor: Albert J. Colli

Patent number: 4029747Abstract: Novel water soluble, inorganic complexes are obtained by reacting, in the presence of aqueous ammonia, at least one non-alkaline metal selected from Groups I-VIII of the Periodic Table with an alkali metal hydroxide. An excess of the non-alkaline metal or metals is introduced into a reaction vessel, preferably already containing the aqueous ammonia, and the alkali metal hydroxide is thereafter incrementally added in such manner as to create localized areas of high concentration and pH approaching a value of 14. The hydrooxide in these areas of high concentration, in combination with reactive NH.sub.2 groups provided by the aqueous ammonia, causes erosion of the non-alkaline metal, the formation of non-alkaline metal ions and the production of a monomeric, metal amide complex.Type: GrantFiled: November 17, 1975Date of Patent: June 14, 1977Assignee: Molecular Energy Research Co., Inc.Inventor: George G.

Patent number: 4010249Abstract: Hydrogen is produced from water by the addition of heat to a series of chemical reactions which comprise the reaction of cadmium with water, and the subsequent recovery of the cadmium for re-use. The equipment used to produce the hydrogen requires only the input of water and heat to produce an output of hydrogen and oxygen gas.Type: GrantFiled: September 15, 1975Date of Patent: March 1, 1977Inventor: Anthony A. DUPont

Patent number: 4005185Abstract: A method for generating hydrogen. Metallic zinc or metallic zinc coated with a film of a dissimilar metal, a dissimiliar metal oxide, or a dissimiliar metal oxide complex is contacted through the medium of an aqueous solution of (i) neutral ammonium carbonate, (ii) neutral ammonium carbonate and an ammonium salt of an inorganic acid, (iii) an ammonium salt of an inorganic acid and ammonia water, or (iv) neutral ammonium carbonate, an ammonium salt of an inorganic acid and ammonia water with an ammonium complex salt of a metal other than zinc.Type: GrantFiled: April 10, 1974Date of Patent: January 25, 1977Inventor: Otaharu Ishizaka

Patent number: RE31788Abstract: Fine metallic nitride powders having a high purity are prepared, without causing any plugging or other problems in the reaction apparatus and with easy heat control of the reaction, by reacting a metallic halide with liquid ammonia in the presence of an organic solvent which has a specific gravity higher than that of liquid ammonia, and also is not miscible or is only slightly miscible with liquid ammonia at a reaction temperature. The process according to the present invention is effected by introducing the metallic halide into the lower organic solvent layer of the reaction system.Type: GrantFiled: December 20, 1982Date of Patent: January 1, 1985Assignee: Ube Industries, Inc.Inventors: Tadashi Iwai, Takashi Kawahito, Tetsuo Yamada
