    Abstract: To produce N2O, ammonium nitrate is decomposed in an aqueous, chloride-containing solution in nitric acid while an ammonia atmosphere is maintained above the reaction mixture. The preferred temperature range of the solution is 110*-125* C. The atmosphere of ammonia is maintained by introducing at least part of the required ammonia into the gas volume of the reaction vessel. The decomposition of the ammonium nitrate and the formation of N2O is enhanced by the presence of catalytically active ions of manganese, copper, cerium, lead, bismuth, cobalt and nickel; manganese, especially in its bivalent form, being preferred.

    Abstract: Tetrafluoro-ethylene can be added to monoamines having oxyethyl or oxypropyl groups in aprotic polar solvents in the presence of alkali metals. The new monoamines obtained having the radicals tetrafluoro-ethyloxy-ethyl or tetrafluoro-ethyl-oxy-propyl are electrolyzed in anhydrous hydrofluoric acid, thus forming new monoamines in which all or nearly all hydrogen atoms of the starting compounds are replaced by fluorine.

    Abstract: 1377084 Antimony pentachloride FARBWERKE HOECHST AG 17 Nov 1971 [6 March 1971] 53472/71 Heading C1A Antimony is recovered as the pentachloride from solutions containing antimony as chloride and/or fluoride, hydrocarbons substituted with chlorine or both chlorine and fluorine and inorganic impurities, by converting any antimony fluorides in the solution to antimony chlorides, distilling off halogenated hydrocarbons to concentrate the solution, establishing the solution at a temperature of at least 60‹ C. to decompose any SbCl 5 in the solution into SbCl 3 and chlorine, separating residual halogenated hydrocarbons and any other organic impurities by extracting with an organic solvent, oxidizing with chlorine the antimony trichloride so obtained to antimony pentachloride and separating the latter from the inorganic impurities. The initial solution may be a spent catalyst solution, obtained in the fluorination of halogenated hydrocarbons using SbCl 5 as catalyst, and generally containing chlorinated or fluorochlorinated hydrocarbons, inorganic and organic impurities, e.g. FeCl 3 and hexachloroethane and antimony chlorides and fluorides (SbF 3 and SbF 5 ). The latter are converted into antimony chlorides by heating the solution suitably at 40‹-130‹ C., the antimony fluorides reacting with chlorinated hydrocarcarbons present and if desired additionally added chlorinated hydrocarbon, e.g. CCl 4 . Halogenated hydrocarbons are distilled off simultaneously or subsequently and the concentrated solution is heated at e.g. 80‹-300‹ C. to decompose SbCl 5 present, the liberated chlorine being used in the rechiorination step. Organic impurities, e.g. fluorinated and chlorinated hydrocarbons, e.g. C 2 Cl 6 are then solvent extracted preferably by contacting with a halogenated hydrocarbon, suitably that obtained in the preceding distillation, at an elevated temperature of up to 100‹ C. and then cooling to not less than 10‹ C. Rechlorination of the SbCl 3 is preferably effected 60‹-150‹ C. at 0-4 atmospheres gauge and the resulting pentachloride separated from inorganic impurities, e.g. FeCl 3 by distillation under reduced pressure.
