Abstract
Abstract Tertiary amines may be prepared by reacting an aldehyde, hydrogen and a nitrogen-containing compound such as ammonia, a primary amine or a secondary amine in the presence of a rhodium- or ruthenium-containing catalyst at temperatures in the range of from about 50° to about 350° C. and a pressure in the range of from about 10 to about 300 atmospheres.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
62 words
A process for the preparation of a tertiary amine which comprises reacting an aldehyde, hydrogen and a nitrogen-containing compound having the formula: ##STR3## in which the R's are independently selected from the group consisting of hydrogen, alkyl, aryl, cycloalkyl, aralkyl, and alkaryl radicals in the presence of a catalyst selected from the group consisting of carbonyls and halocarbonyls of rhodium and ruthenium.
Claim 2
Dependent Claim
62 words
