Abstract

Reivindicacion 1: Procedimiento para la fabricacion de melamina transformando urea en presencia de un catalizador solido en uno o varios reactores conectados en serie en el margen de temperatura de 370 °C a 430 C, enfriando y filtrando el gas obtenido en la transformacion con urea, separando la melanina por desublimacion y reciclando una parte del gas presente después de la separacion de melamina (ôgas de circulacionö) al reactor o los reactores, cuyo procedimiento está caracterizado porque todos los pasos de síntesis arriba indicados se realizan a una presion en la region de 4 bar abs. a 10 bar abs.
