Abstract

QUE COMPRENDE LA DILATACION DE LA QUITINA DE PARTICULA CON UNA SOLUCION ACUOSA A UNA TEMPERATURA INFERIOR A 30°C Y DURANTE AL MENOS 36 HORAS, Y LUEGO HACER REACCIONAR LA QUITINA DE PARTICULA DILATADA RESULTANTE CON UNA SOLUCION ALCALINA A UNA TEMPERATURA ENTRE 45°C Y 120°C, PARA ORIGINAR LA DEACETILACION. SE APLICA PRESION Y/O IRRADIACION PARA ACELERAR LA DILATACION. EL QUITOSAN SE AISLA LAVANDO LA QUITINA DEACETILADA CON AGUA HASTA QUE LA SOLUCION DE LAVADO LLEGUE A SER NEUTRA, Y LUEGO SECAR Y MOLER EL PRODUCTO DE QUITOSAN
