摘要
The present invention provides a process for preparing N-methylated melamines in simple steps by using inexpensive raw materials in such a manner that the proportion of mono-type, bis-type and tris-type of the N-methylated melamines as prepared can be controlled. The process comprises reacting by heating melamine with methylamine in the presence of an acidic catalyst under pressure to substitute at least one amino group of the melamine by methylamino group.
