ABSTRACT:
A method is provided for the preparation of tertiary polyamines by alkylating a polyamine having at least two primary amino groups without the use of excess solvent. More particularly, a tertiary amine is produced by reductively alkylating a polyamine with a carbonyl compound, such as formaldehyde, in a reaction zone while in the presence of a hydrogenation catalyst and hydrogen under reductive conditions. The carbonyl compound is continuously supplied to the reaction zone.
