Abstract

METODO MEJORADO PARA LA METILOLACION DE MATERIALES LIGNINA, A PARTIR DE LAS AGUAS NEGRAS DE UN PROCESO DE REDUCCION A PASTA KRAFT EN EL QUE LOS COMPONENTES LIGNINA PUEDEN SER METILOLATADAS IN SITU EN LAS AGUAS NEGRAS ANTES DE SU AISLAMIENTO PARA TRATAMIENTO SUBSIGUIENTE O USO COMO UN ADITIVO QUIMICO EN OTRAS APLICACIONES QUIMICAS Y, MAS ESPECIFICAMENTE, ES PROPORCIONAR UN METODO MEJORADO PARA PRODUCIR UNA SAL DE LIGNINA SULFOMETILADA CON BAJO CONTENIDO EN ELECTROLITO A PARTIR DE LAS AGUAS NEGRAS DE UN PROCESO DE REDUCCION A PASTA KRAFT QUE ES ADECUADA PARA UTILIZAR COMO UN ADITIVO QUIMICO EN OTRAS APLICACIONES TALES COMO DISPERSANTES DE TINTES, DONDE EL MATERIAL LIGNINA NO NECESITA SER AISLADO DE LAS AGUAS NEGRAS DEL PROCESO DE REDUCCION A PULPA ANTES DE SU METILOLACION.
