Title:
PROCESS FOR THE PREPARATION OF ALKYLENEBISMELAMINES
Document Type and Number:
WIPO Patent Application WO/2000/017171
Kind Code:
A1
Abstract:
A process which enables easy and inexpensive preparation of alkylenebismelamine derivatives usable as components for forming resin materials including aminoplasts, and flame-retardant materials. Specifically, a process for the preparation of alkylenebismelamines wherein the alkylene is a C¿2?-C¿10? linear or branched one by reacting an alkylenediamine wherein the alkylene is a C¿2?-C¿10? linear or branched one with melamine under heating in the presence of an acidic catalyst, characterized in that the amount of melamine is at least twice that of the alkylenediamine by mole.
