Abstract

Se proporciona un método para preparar un éter de celulosa no iónico soluble en agua que tiene bajo contenido insoluble y que proporciona una solución transparente. Más específicamente, se proporciona un método para preparar un éter de celulosa no iónico soluble en agua que comprende al menos las etapas de: secar una hoja de pasta papelera o las astillas de pasta papelera en las cuales se ha convertido la hoja de pasta papelera, poner en contacto la hoja de pasta papelera o las astillas de pasta papelera secas con una solución de hidróxido de metal alcalino para obtener celulosa alcalina, drenar la celulosa alcalina y hacer reaccionar la celulosa alcalina drenada con un agente eterificante.
