  • Process for preparing monoisopropylamine
    Patent number: 6563004
    Abstract: Monoisopropylamine is prepared by reacting acetone with ammonia and with hydrogen at elevated temperature and elevated pressure in the presence of a catalyst, wherein the catalytically active mass of the catalyst comprises, after its preparation and before the treatment with hydrogen, from 20 to 90% by weight of aluminum oxide (Al2O3), zirconium dioxide (ZrO2), titanium dioxide (TiO2) and/or silicon dioxide (SiO2), from 1 to 70% by weight of oxygen-containing compounds of copper, calculated as CuO, from 1 to 70% by weight of oxygen-containing compounds of nickel, calculated as NiO, and from 1 to 70% by weight of oxygen-containing compounds of cobalt, calculated as CoO.

  • Catalysts for the amination of alkylene oxides, alcohols, aldehydes and ketones
    Patent number: 5958825
    Abstract: A catalyst comprising, based on the total weight of the catalyst,more than 6-50% by weight of cobalt, nickel or a mixture thereof,0.001-25% by weight of ruthenium,0-10% by weight of copper and0-5% by weight of promoterson a porous metal oxide carrier can be prepared by(a) impregnating the carrier with the metals, promoters or compounds thereof,(b) drying and calcining the impregnated carrier and(c) reducing the calcined carrier in a stream of hydrogen,carrier not being impregnated with halogen compounds.
