  • Process for the dehalogenation of organic compounds
    Patent number: 5490919
    Abstract: Organohalides are dehalogenated by bringing an organohalide or a mixture of two or more organohalides into contact with an alkali hydroxide in an alcoholic solution and in the presence of a catalytically effective amount of a heterogeneous transfer hydrogenolysis catalyst. The process can be carried out at relatively low temperatures (50.degree.-150.degree. C.) and at low pressures. No added hydrogen is employed, in excess of that contained in the ambient atmosphere.
    Type: Grant
    Filed: June 27, 1994
    Date of Patent: February 13, 1996
    Assignee: State of Isreal, Atomic Energy Commission
    Inventors: Ilan Pri-Bar, David Azoulay, Ouri Buchman

  • Production of aldehydes
    Patent number: 4605749
    Abstract: There is provided a process for the production of aldehydes wherein an oric halide is reacted with carbon monoxide at a superatmospheric pressure in the presence of a hydrogen donor and in the presence of a base and of a catalyst in a solvent system.Catalysts of choice are transition metal catalysts. A preferred temperature range is from about 50.degree. to 150.degree. C.
