Abstract
Tertiary amines such as alkyl or benzyl amines are catalytically oxidized by oxygen over an activated carbon catalyst to selectively produce secondary amines.
Claims15
A process for the production of secondary amines which comprises contacting a tertiary amine with oxygen and carbon at a temperature sufficient to oxidize the amine and effect removal of a group attached to the nitrogen thereof, the temperature being in the range of ambient temperatures up to about 250.degree. C., the group being selected from the class consisting of alkyl, aralkyl and hydroxyalkyl, and in which the other groups on the nitrogen are selected from the aforesaid class or groups relatively more stable to oxidative removal than the aforesaid class, and obtaining the resulting secondary amine in substantial yield.
