Abstract:
The invention relates to a method for producing an amine by reacting a primary or secondary alcohol, aldehyde and/or ketone with hydrogen and a nitrogen compound, selected from the group including ammonia, primary and secondary amines, in the presence of a zirconium dioxide-containing, copper-containing and nickel-containing catalyst, the catalytically active mass of the catalyst prior to its reduction with hydrogen containing oxygen-containing compounds of zirconium, copper, nickel, 0.2 to 40% by weight of oxygen-containing compounds of cobalt, calculated as CoO, 0.1 to 5% by weight of oxygen-containing compounds of iron, calculated as Fe2O3, and 0.1 to 5% by weight of oxygen-containing compounds of lead, tin, bismuth and/or antimony, each calculated as PbO, SnO, Bi2O3 or Sb2O3. The invention also relates to catalysts of the above type.

The invention also relates to catalysts of the above type.
Abstract:
Disclosed is a method for producing an amine by reacting a primary or secondary alcohol, aldehyde, and/or ketone with hydrogen and a nitrogen compound selected from among the group comprising ammonia and primary and secondary amines in the presence of a catalyst containing zirconium dioxide, copper, and nickel. Before being reduced with hydrogen, the catalytically active material of the catalyst contains oxygen-containing compounds of zirconium, copper, and nickel, 1.0 to 5.0 percent by weight of oxygen-containing compounds of cobalt, calculated as CoO, and 0.2 to 5.0 percent by weight of a polyoxometallate. Also disclosed are catalysts as defined above.
Abstract:
Method for producing ethylamines and monoisopropylamine (MIPA), in which bioethanol is reacted with ammonia in the presence of hydrogen and a heterogeneous catalyst to form ethylamines, wherein the bioethanol contains sulphur and/or sulphur-containing compounds of ≥ 0.1 ppm by weight (calculated S), and then in the presence of the same catalyst, isopropanol is reacted with ammonia in the presence of hydrogen to form MIPA.
