Abstract
EL OBJETO DE LA INVENCION ES OPTIMIZAR UN PROCEDIMIENTO PARA LA PRODUCCION DE ACIDOS POLICARBOXILICOS O SUS SALES A PARTIR DE POLISACARIDOS, MEDIANTE LA OXIDACION CON DIOXIDO DE NITROGENO GASEOSO/TETRAOXIDO DE DINITROGENO, TRANSFORMANDO AL MENOS UNA PARTE DE LOS GRUPOS DE ALCOHOL PRIMARIO DE LOS POLISACARIDOS EN GRUPOS CARBOXILOS Y, DADO EL CASO, NEUTRALIZANDO, AL MENOS PARCIALMENTE, LOS GRUPOS DE ACIDO CARBOXILICO PRODUCIDOS. EN PARTICULAR ESTO SE CONSIGUE LLEVANDO EL DIOXIDO DE NITROGENO/TETRAOXIDO DE DINITROGENO A UNA TEMPERATURA DE CARGA DENTRO DEL MARGEN DEL PUNTO DE EBULLICION DEL DIOXIDO DE NITROGENO, A LA PRESION CORRESPONDIENTE HASTA ALCANZAR UNA TEMPERATURA QUE SE ENCUENTRA POR ENCIMA DE LOS 50 (GRADOS) C, SIENDO ABSORBIDO, AL MENOS PARCIALMENTE, POR EL POLISACARIDO, Y OXIDANDOSE DESPUES LOS GRUPOS DE ALCOHOL PRIMARIO EN GRUPOS CARBOXILOS A UNA TEMPERATURA DE OXIDACION QUE ESTA AL MENOS 10 (GRADOS) C POR ENCIMA DE LA TEMPERATURA DE CARGA.
