Abstract

SE PRESENTAN PROCESOS PARA LA PREPARACION DE DERIVADOS DE POLIGLUCOSAAMINAS, POR EJEMPLO, QUITOSANO HIDROXIPROPILO Y QUITOSANO CARBOXIMETILO. LOS DERIVADOS DE POLIGLUCOSAMINA PUEDEN SER PREPARADOS EN UNA FORMA DE ENLACE COVALENTE UTILIZANDO UN MEDIO CAUSTICO DILUIDO O UNA FORMA IONICAMENTE ENLAZADA. SE PUEDEN EVITAR BASES FUERTES Y SOLVENTES ORGANICOS INMISCIBLES EN AGUA INDESEABLES. LOS DERIVADOS COVALENTEMENTE ENLAZADOS SE DISUELVEN EN EL MEDIO CAUSTICO DILUIDO EN LA FORMACION. TAMBIEN SE PRESENTAN LAS COMPOSICIONES QUE CONTIENEN LOS DERIVADOS Y LOS USOS PARA LOS MISMOS.
