  • Process for preparing oxygen-containing organic compounds
    Patent number: 4673693
    Abstract: A process for preparing oxygen-containing organic compounds from synthesis gas which comprises contacting the synthesis gas with a solid catalyst prepared by the steps of: mixing (A) a copper compound, (B) a nickel compound and (C) a zinc compound; calcining the mixture; mixing the calcined product with (D) a potassium compound; and then reducing the resulting mixture.The selectivity of alcohols such as ethanol and propanol is high in the process of the present invention. The catalyst of the present invention can be used effectively over long periods of time, since the dissipation of the nickel component in the catalyst during the reaction is decreased.
