Abstract

HAY DESCRITO UN METODO PARA PURIFICAR UNA SOLUCION DE N-OXIDO DE N-METILMORFOLINA ACUOSA UTILIZADA RECUPERADA A PARTIR DE UNA SOLUCION ACUOSA GIRATORIA, QUE RESULTA DE UNA SOLUCION DE COAGULACION EN LA QUE UN COMPUESTO DE CELULOSA QUE CONTIENE NOXIDO DE N-METILMORFOLINA ES EXPULSADO A TRAVES DE UNA EXTINCION GIRATORIA DE UNA SOLUCION DE LAVADO PARA LOS ARTICULOS CELULOSICOS COAGULADOS EN PROCESOS DE FABRICACION DE FIBRAS DE CELULOSA O PELICULAS, QUE COMPRENDE AÑADIR UN OXIDANTE A LA SOLUCION DE N-OXIDO DE N-METILMORFOLINA ACUOSA UTILIZADA PARA ELIMINAR IMPUREZAS DE LA MISMA A TRAVES DE LA OXIDACION NMETILMORFOLINA A N-OXIDO DE N-METILMORFOLINA Y ROMPER LOS CROMOFOROS DE LAS IMPUREZAS. COMPLETAMENTE DISTINGUIDO DE LOS METODOS CONVENCIONALES EN EL PRINCIPIO, EL METODO ES MUY SIMPLE Y EFICIENTE ASI COMO SUPERIOR A LOS METODOS CONVENCIONALES QUE UTILIZAN RESINA DE INTERCAMBIO IONICO EN LA DECOLORACION. ADEMAS, NO NECESITA SUFRIR UNA PERDIDA DE OXIDO DE AMINAS COMO ES USUAL EN LA RESINA DE INTERCAMBIO IONICO. ADEMAS, EL OXIDANTE PUEDE LOGRAR LA DECOLORIZACION SIN LA INFLUENCIA DE LA CONCENTRACION DE OXIDOS DE AMINAS. EL OXIDO DE AMINA DECOLORIZADO POR EL OXIDANTE PUEDE SER UTILIZADO PARA PREPARAR EL COMPUESTO DE CELULOSA SIN NINGUNA OTRA PURIFICACION. CON LA UTILIZACION SECUENCIAL DEL OXIDANTE Y LA RESINA O CARBON ACTIVO, HAY QUE TENER UNA EFICIENCIA MUCHO MAS ALTA ASI COMO UNA SOLUCION DE OXIDO DE AMINA ACUOSA MUCHO MAS PURA.
