Process for preparing primary amines which have at least one functional group of the formula (—CH
2
—NH
2
) and at least one further primary amino group by alcohol amination of starting materials having at least one functional group of the formula (—CH
2
—OH) and at least one further functional group (—X), where (—X) is selected from among hydroxyl groups and primary amino groups, by means of ammonia with elimination of water, wherein the reaction is carried out homogeneously catalyzed in the presence of at least one complex catalyst comprising at least one element selected from groups 8, 9 and 10 of the Periodic Table and also at least one donor ligand.

Preparing a primary amine by alcohol amination of alcohol with ammonia and elimination of water includes reacting, in a homogeneously catalyzed reaction, a mixture of alcohol, ammonia, nonpolar solvent, and catalyst, in a liquid phase, to obtain a product mixture. The process then includes phase separating the product mixture into a polar product phase and a nonpolar product phase, and separating off the nonpolar product phase. At least some of the nonpolar phase returns to the homogenously catalyzed reaction. The process further includes separating off amination product from the polar product phase. At least some of the catalyst is in the nonpolar phase, and the catalyst accumulates in the nonpolar phase.

Process for preparing alkanolamines which have a primary amino group (—NH
2
) and a hydroxyl group (—OH) by alcohol amination of diols having two hydroxyl groups (—OH) by means of ammonia with elimination of water, wherein the reaction is carried out homogeneously catalyzed in the presence of at least one complex catalyst comprising at least one element selected from groups 8, 9 and 10 of the Periodic Table and also at least one donor ligand.
