Abstract

"éTERES DE CELULOSE E MéTODO PARA PREPARá-LOS". A presente invenção provê um método de preparação de éteres de celulose compreendendo as etapas de (a) obter polpa de celulose mercerizada e recuperada, e (b) converter a polpa de celulose, mercerizada e recuperada, em éteres de celulose. Quando a polpa de celulose é kraft de madeira dura do sul, a polpa de celulose mercerizada tem uma viscosidade TAPPI 230 om-89 maior que 12 cP. Tipicamente, a polpa de celulose mercerizada é substancialmente livre de celulose III. A polpa de celulose preparada por este método, tem uma porcentagem maior de celulose cristalina II e uma área cristalina menor que a da polpa de celulose não mercerizada. A presente invenção provê também um método de preparação de um flóculo de celulose compreendendo as etapas de (a) obter polpa de celulose mercerizada e recuperada, e (b) tratar a polpa de celulose formando o flóculo de celulose.
