Abstract
Abstract Tertiary amines may be prepared by reacting an olefinic compound, carbon monoxide, 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: 11
Claim 1
Independent Claim
73 words
A process for the preparation of tertiary amines which comprises reacting an olefinic compound, carbon monoxide, 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, aralykyl and alkaryl radicals in the presence of a rhodium catalyst selected from the group consisting of rhodium metal, nitrate, halides, chlorodicarbonylrhodium dimer and chlorobis(ethylene)rhodium dimer, and recovering the resultant tertiary amine.
Claim 2
Dependent Claim
73 words
A process for the preparation of tertiary amines which comprises reacting an olefinic compound, carbon monoxide, 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, aralykyl and alkaryl radicals in the presence of a rhodium catalyst selected from the group consisting of rhodium metal, nitrate, halides, chlorodicarbonylrhodium dimer and chlorobis(ethylene)rhodium dimer, and recovering the resultant tertiary amine.
Claim 3
Dependent Claim
