Abstract: The present invention relates to the production and purification of melamine and, in particular, to the purification of a crude melamine product, while minimizing impurities comprising at least one of melem, melam, melon, or ureidomelamine. The crude melamine can be treated with ammonia and a promoter to achieve a very high melamine content in the purified product, at more advantageous conditions, than treatment with ammonia alone. The present invention is also directed to an improved melamine production process that yields melamine with so few impurities that it can be pure enough as to not require an additional purification step.
