Disclosed are catalysts, the catalytically active mass of which contains 22 to 40 percent by weight of oxygen-containing compounds of zirconium, calculated as ZrO, 1 to 30 percent by weight of oxygen-containing compounds of copper, calculated as CuO, 15 to 50 percent by weight of oxygen-containing compounds of nickel, calculated as NiO, the molar ratio between nickel and copper being greater than 1, 15 to 50 percent by weight of oxygen-containing compounds of cobalt, calculated as CoO, and less than 1 percent by weight of an alkali metal, calculated as alkali metal oxide, prior to being treated with hydrogen. Also disclosed is a method for the production of amines by reacting primary and secondary alcohols, aldehydes, or ketones with hydrogen and nitrogen compounds selected from the group ammonia, primary and secondary amines, in the presence of said catalysts at an elevated temperature and an elevated pressure.

Catalysts and method for the production of amines

The present invention relates to a process for the preparation of N-substituted 2,6-dialkylmorpholines of the formula I in which Rand R, independently of one another, are hydrogen, alkyl or cycloalkyl, or Rand Rtogether with the carbon atom to which they are bonded are a 5- to 14-membered carbocycle, and Rand R, independently of one another, are alkyl or cycloalkyl, by reacting at least one carbonyl compound of the formula II in which Rand Rhave the meanings given above, with at least one morpholine of the formula III in which Rand Rhave the meanings given above, in the presence of hydrogen and at least one metal-containing catalyst, wherein the active component of the catalyst consists essentially of platinum group metals.
