Method for producing N-methylated amine compounds

The use of a sulfur and active metal catalyst in an atmosphere of carbon dioxide and hydrogen for methylation of aliphatic amines addresses the health risks of formaldehyde in existing methods, achieving high yields of N-methylated amine compounds.

Abstract

The present invention aims to provide a method for producing N-methylated amine compounds that does not require formaldehyde and can produce N-methylated amine compounds in excellent yield. [Solution] A method for producing an N-methylated amine compound, characterized by heating an aliphatic amine compound having at least one amino group in its molecule to 50 to 250°C in an atmosphere in which carbon dioxide at 0.1 to 10 MPa (gauge pressure) and hydrogen at 0.1 to 20 MPa (gauge pressure) are introduced, in the presence of a catalyst on which a sulfur element and an active metal element are supported on a carrier, thereby methylating the amino group.
