Abstract

UN PROCESO PARA LA FABRICACION DE ACIDOS POLIAMINO, PARTICULARMENTE ACIDOS POLIASPARTICOS. UN AMINOACIDO SOLIDO, EN PARTICULAS, SE FLUIDIZA POR AGITACION EN UNA ATMOSFERA DE NITROGENO Y SE CALIENTA A UNA TEMPERATURA DE AL MENOS 180 TIENE A TAL TEMPERATURA DURANTE UNA CANTIDAD DE TIEMPO SUFICIENTE PARA POLIMERIZAR EL AMINO ACIDO Y PARA EXPULSAR AGUA DESDE EL LECHO CALENTADO. SE PROPORCIONA UN GRADO DE AGITACION SUFICIENTE PARA FLUIDIZAR SUSTANCIALMENTE LAS PARTICULAS Y SE MANTIENE A TRAVES DEL PROCESO UN TAMAÑO DE PARTICULA DE NO MAS DE 150 MICRAS. EL ACIDO ANHIDROPOLIAMINO RESULTANTE ES ENTONCES HIDROLIZADO A UN ACIDO POLIAMINO.
