Abstract

Se describe un método para producir celulosa microcristalina blanqueada, dicho método comprende neutralizar o alcalinizar una lechada de mezcla de reacción de producción microcristalina ácida, típicamente producida por hidrólisis ácida o por irradiación de haz electrónico, seguido por la adición de un oxidante a dicha mezcla de reacción. La práctica de este método permite la producción de celulosa microcristalina teniendo una deseable estabilidad de color así como características de compresión adecuadas para el uso de aglutinante farmacéutico de grado de papel y otras pulpas de baja pureza.
