Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PERFECCIONADO DE OXIDACION ALCALINA Y EN MEDIO ACUOSO DE AZUCARES QUE POSEEN UNA O VARIAS FUNCIONES DE ALCOHOLES PRIMARIOS MEDIANTE HIPOHALITOS Y EN PRESENCIA DE UN CATALIZADOR CONSTITUIDO POR UN NITROXILO ACILO BINARIO O TERCIARIO. EL PROCEDIMIENTO SE CARACTERIZA PORQUE LA OXIDACION SE DESARROLLA EN PRESENCIA DE CONCENTRACIONES ELEVADAS DE AZUCARES. LOS PRODUCTOS OBTENIDOS POR EL PROCEDIMIENTO, NUEVOS PARA ALGUNOS, PUEDEN SER UTILIZADOS COMO BUILDERS EN LAS COMPOSICIONES DE LIXIVACION.
