Abstract

LA PRESENTE INVENCION SE REFIERE A UN PROCESO PARA LA ELABORACION Y REACONDICIONAMIENTO DE LOS N NOS SOLUBLES EN MEDIOS ACUOSOS, TENIENDO EN CUENTA LAS SIGUIENTES MEDIDAS ROXIALQUILIZACION SUBSIGUIENTE DEL CITOSANO DISPERSADO Y CONDICIONAMIENTO A CONTINUACION DEL N QUE ESTA CARACTERIZADO, PORQUE LA HIDROXIALQUILIZACION SE REALIZA CON UN GRADO DE SUSTITUCION MEDIO (DS) DESDE 2.0, CON PREFERENCIA 1.5, HASTA 2.0. DESPUES DE LA HIDROXIALQUILIZACION Y DEL REACONDICIONAMIENTO, SE SEPARA EVENTUALMENTE UNA PARTE DEL MEDIO ACUOSO Y EL REACONDICIONAMIENTO SE CONSIGUE MEDIANTE UN SECADO DEL N - HIDROXIALQUIL CITOSANO.
