Gas-phase oxidative coupling of alcohols and amines using heterogeneous catalysts

Abstract

Disclosed are methods of forming an N,N-substituted-formamide comprising contacting a feed gas comprising an alcohol and an N,N-substituted-amine with a solid heterogeneous catalyst in the presence of an oxidizing agent at a reaction temperature, wherein the solid heterogeneous catalyst comprises one or more noble metals; and oxidatively coupling the feed gas under conditions effective to form an effluent gas comprising the N,N-substituted-formamide. Also disclosed herein are methods of forming a carbamide and/or a carbamate comprising contacting a feed gas comprising an alcohol and an N,N-substituted-amine with a solid heterogeneous catalyst in the presence of an oxidizing agent at a temperature greater than or equal to 155° C., wherein the solid heterogeneous catalyst comprises one or more noble metals; and oxidatively coupling the feed gas under conditions effective to form a product gas comprising the carbamide and/or carbamate.
