Abstract

SE DESCRIBE UN PROCEDIMIENTO PARA LA ACTIVACION DE POLISACARIDOS, EN EL QUE EL MATERIAL DE PARTIDA POLISACARIDO SE PONE EN CONTACTO CON AMONIACO LIQUIDO A UNA PRESION INICIAL SUPERIOR A LA PRESION ATMOSFERICA Y A UNA TEMPERATURA DE AL MENOS APROXIMADAMENTE 25 IQUIDO AL MENOS PARA LA HUMECTACION DE LA SUPERFICIE DEL MATERIAL DE PARTIDA POLISACARIDO, EXPANDIENDOSE ESTE A CONTINUACION, EN EL QUE EL VOLUMEN DISPONIBLE PARA EL SISTEMA POLISACARIDO/AMONIACO LIQUIDO SE AUMENTA DISMINUYENDO LA PRESION AL MENOS EN 5 BARES Y PRODUCIENDOSE UNA EXPLOSION. EL PROCEDIMIENTO ES ESPECIALMENTE APROPIADO PARA LA ACTIVACION DE CELULOSA, GOMA DE GUAR, ALMIDON Y QUITINA. MEDIANTE EL PROCEDIMIENTO SE CONSIGUE UNA MODIFICACION DE LA CELULOSA NUEVA. LOS POLISACARIDOS ACTIVADOS PRESENTAN UNA MAYOR REACTIVIDAD, ELIMINANDOSE MEJOR LOS REACTIVOS DURANTE LA ACILACION, ALQUILACION, SILILACION, XANTOGENACION Y CARBAMOILACION CON UNOS PROCESOS DE REACCION MUY HOMOGENEOS.
