Abstract

SE PRESENTA UN PROCESO PARA PRODUCIR UN COMPUESTO DISPERSANTE DE LIGNINA QUE CONTIENE LOS PASOS DE METILOLIZAR UN COMPUESTO DE LIGNINA MEDIANTE LA REACCION DE MENOS DE 2 MOLES DE FORMALDEHIDO POR 1000 GR DE LIGNINA, Y SULFONATIZAR LA LIGNINA DILATADA MEDIANTE LA REACCION DE DESDE 2.5 HASTA 3.5 MOLES DE UN COMPUESTO DE SULFITO O BISULFITO POR 1000 GR. DE LIGNINA EN UN PH DE REACCION INICIAL POR DEBAJO DE 6.6. Y A UNA TEMPERATURA DE AL MENOS 170 (GRADOS) C, MIENTRAS SE PERMITE QUE EL PH DE LA MEZCLA DE REACCION ALCANCE UN PH FINAL MAYOR QUE 7.5 PARA SECUENCIALMENTE SULFOMETILATAR EL NUCLEO AROMATICO Y SULFONATAR LA ARENA LATERAL DE LIGNINA. LOS PRODUCTOS DEL METODO ENCUENTRAN UN USO PARTICULAR COMO DISPERSANTES EN COMPOSICIONES COLORANTES Y COMPOSICIONES DE NEGRO CARBON CON VISCOSIDAD INFERIOR Y UNA VIDA MEDIA DE ALMACENAMIENTO MAS LARGA DEL COMPUESTO.
