The present invention relates to a chemocatalytic liquid-phase process for the direct one-stage amination of alcohols to primary amines by means of ammonia in high yields using a catalyst system containing at least one transition metal compound and a xantphos ligand.

Process for the direct amination of alcohols using ammonia to form primary amines by means of a xantphos catalyst system

The invention relates to a process for preparing primary amines which comprises the process steps

Process for the direct amination of secondary alcohols with ammonia to give primary amines

The present invention relates to a process for preparing primary amines comprising the process steps

Process for homogeneously catalyzed, highly selective direct amination of primary alcohols with ammonia to primary amines with a high volume ratio of liquid phase to gas phase and/or high pressures

The invention provides a method to produce primary diamines by catalytic conversion of diols having a linear main chain of from 4 to 31 carbon atoms into the corresponding diamines. The reaction is conducted in a liquid or supercritical phase and is catalyzed by a homogeneous ruthenium-containing complex. The primary diamines obtained may be suitable for polyamide syntheses.
