Abstract
Método para preparar éteres de celulosa, masa flocosa de celulosa realizada mediante el método, éter de celulosa ionico, no-ionico, metil celulosa ycarboximetil celulosa realizados mediante el método y una carboximetil celulosa obtenida mediante elm étodo. Los presentes inventores han descubierto que lareología de la ssoluciones de éteres de celulosa preparados a partir de pulpa de celulosa es alterada por la mercerizacion y recuperacion de la pulpa decelulosa antes de preparar los éteres decel ulosa. Por ejemplo, la viscosidad de la solucion de la carboximetil celulosa (CMC) producida a partir de la pulpade celulosa mercerizada y recuperada es significativamente superior a la producida a partir de la pulpa de celulosa no mercerizada.La pr esente invencionprovee un método para prepara éteres de celulosa que comprende las etapas de (a) obtener pulpa de celulosa mercerizada y recuperada, y (b) convertir la pulpade celulosa mercerizada y recuperada en éteres de celulosa. Cuando lapulpa d e celulosa es pulpa kraft de madera blanda del sur, la pulpa de celulosamercerizada tiene una viscosidad TAPPI 230 om-89 superior a 12cP. La pulpa de celulosa mercerizada está típicamente sustancialmente libre de celulosa III. Lapulpa decelulosa mer cerizada preparada por este método tiene un mayor porcentaje de celulosa cristalina II y un área cristalina menor que para la pulpa decelulosa no mercerizada. La presente invencion provee también un método para preparar una masa flocosade celulosa q ue comprende las etapas de (a) obtenerpulpa de celulosa mercerizada y recuperada, y (b) tratar la pulpa mercerizada para formar la masa flocosa de celulosa. Cuando la pulpa de celulosa es kraft demadera blanda del sur, la pulpa decelulosa mercerizad a tiene una viscosidad TAPPI 230 om-89 superior a 12cP. Alternativamente el método comprende mercerizary recuperar una masa flocosa de celulosa. La masa flocosa de celulosa preparada mediante este método tiene mayor densidad demasa que la masa de ce lulosapreparada a partir de pulpa de celulosa similar no mercerizada. Además el aumento de la densidad de masa es superior al esperado por el aumento de la aspereza
