Abstract
Se utilizan las etilénaminas en el lavado de la pulpa, para remover la lignina. Un proceso para lavar una mezcla de pulpa y celulosa, que contienelignina, para remover por lo menos una porción de la lignina de la misma, comprende la utilización de una composición de lavado que tiene por lo menos100 ppm de una etilénamina. El proceso incluye una mejora en un proceso para el lavado de una mezcla celulosa y pulpa que contiene lignina, en el cual procesose utiliza una composición de lavado para remover por lo menos una porción de la lignina, comprendiendo la mejora, la utilización de por lo menos 100 ppm deuna etilénamina junto con la composición de lavado y/o la utilización de una cantidad de etilénamina por lo menos equivalente a 100 ppm, basado en lacomposición de lavado, junto con la composición de lavado. La composición de lavado es también novedosa e incluye una composición de lavado para lavar lapulpa Kraft, que comprende agua y por lo menos 100 ppm de una etilénamina.
