Abstract
PARA MEJORAR UN PROCEDIMIENTO PARA LA PREPARACION DE SALES DE ACIDO POLICARBOXILICO MEDIANTE LA OXIDACION DE POLISACARIDOS CON DIOXIDO DE NITROGENO/TETRAOXIDO DE DINITROGENO GASEOSO Y TRANSFORMANDO AL MENOS UNA PARTE DE LOS GRUPOS DE ALCOHOL PRIMARIO DE LOS POLISACARIDOS EN GRUPOS CARBOXILOS, ASI COMO NEUTRALIZANDO AL MENOS PARCIALMENTE LOS GRUPOS DE ACIDO CARBOXILICO RESULTANTES, DE FORMA QUE SEA MAS FACIL PREPARAR PRODUCTOS DE NEUTRALIZACION SOLIDOS, EL ACIDO POLICARBOXILICO SOLIDO ES MEZCLADO CON UN AGENTE DE NEUTRALIZACION SOLIDO. LOS POLICARBOXILATOS OBTENIDOS SON UTILIZADOS, POR EJEMPLO, COMO BUILDERS O CO-BUILDERS EN PRODUCTOS DE LAVADO O LIMPIEZA.
