<P>PROBLEM TO BE SOLVED: To provide a method of producing a secondary or tertiary higher amine. <P>SOLUTION: The method of producing a higher amine comprises allowing a primary or secondary amine to react with an alcohol in the presence of at least one species of hydrogen halide selected from hydrogen chloride, hydrogen bromide and hydrogen iodide, or in the presence of a compound capable of producing a hydrogen halide (such as 1,3,5-triazo-2,4,6-triphosphorine-2,2,4,4,6,6-chloride). If the raw material amine is a primary amine, a secondary higher amine and a tertiary higher amine can be produced. If the raw material amine is a secondary amine, a tertiary higher amine can be produced. <P>COPYRIGHT: (C)2012,JPO&INPIT |
