Abstract
Procedimiento para producir un precursor de una solución de celulosa en un óxido de amina terciaria, caracterizado porque comprende suspender celulosa en un óxido de amina conteniendo agua, hasta que el óxido de amina es absorbido por la celulosa, a una temperatura a la cual no se disuelve la celulosa, para proporcionar un producto sólido de celulosa que contiene óxido de amina absorbido, el cual, tras el calentamiento, se convierte en una solución de celulosa.
