Patent number: 6576159Abstract: The invention is related to ionic compounds, derivatives of malononitrile, in which the anionic load has been displaced. An ionic compound disclosed by the invention includes an anionic portion combined with at least one cationic portion M+m in sufficient number to ensure overall electronic neutrality; the compound is further comprised of M as a hydroxonium, a nitrosonium NO+, an ammonium —NH4+, a metallic cation with the valence m, an organic cation with the valence m, or an organometallic cation with the valence m. The anionic portion corresponds to one of the formulas RD—Y—C(C≡N)2− or Z—C(C≡N)2− in which Z is an electroattractive group, RD is an organic radical, and Y is a carbonyl, a thiocarbonyl, a sulfonyl, a sulfinyl, or a phosphonyl. The compounds can be used notably for ionic conducting materials, electronic conducting materials, colorants, and the catalysis of various chemical reactions.Type: GrantFiled: August 9, 2000Date of Patent: June 10, 2003Assignees: Hydro-Quebec, Centre National de la Recherche ScientifiqueInventors: Christophe Michot, Michel Armand, Michel Gauthier, Yves Choquette

Patent number: 4745207Abstract: Reaction products of hydrogen cyanide are prepared by a process in which hydrogen cyanide prepared in a conventional manner by pyrolysis at from 250.degree. to 650.degree. C. over a solid under from 5 to 200 mbar is cooled to a temperature of from 200.degree. to -10.degree. C. together with the other pyrolysis products, the hydrogen cyanide is then fed to a chemisorption reaction with a base or with a carbonyl compound, and the reaction products of hydrogen cyanide which are formed therein are removed from the system and brought to atmospheric pressure. In this process, the handling of large amounts of hydrogen cyanide is avoided.Type: GrantFiled: November 25, 1985Date of Patent: May 17, 1988Assignee: BASF AktiengesellschaftInventors: Fritz Brunnmueller, Karlheinz Stecher, Michael Kroener, Rolf Schneider
