Abstract
Process for preparing alkanolamines which have a primary amino group (—NH2) 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.
Claims20
A process for preparing an alkanolamine comprising a primary amino group (—NH2) and a hydroxyl group (—OH), the process comprising:
- aminating a diol comprising two hydroxyl groups (—OH) with ammonia, to eliminate water and obtain the alkanolamine,
- wherein the aminating is homogeneously catalyzed in the presence a complex catalyst comprising at least one element selected from groups consisting of 8, 9, and 10 of the Periodic Table, and a donor ligand.
