Abstract
Un procedimiento de preparación de celulosa alcalina partiendo de una materia prima que contiene celulosa por reacción de la materia prima con una lejía alcalina de impregnación, caracterizado porque la materia prima usada es pasta de celulosa fabricada por cocción con álcali sin hidrólisis previa, y/o por cocción con ácido sin extracción con álcali, cuando a la pasta de celulosa, la lejía alcalina de impregnación y/o la celulosa alcalina se añade por lo menos un compuesto orgánico que es un alcohol, un éster, un éter, una cetona, una amina, un ácido o la sal de uno de tales ácidos, una amina o un hidrocarburo alifático que posee por lo menos cuatro átomos de carbono.
