Abstract

Методът намира приложение в целулозната промишленост. Той е икономичен, екологичен и сигурен. По метода се смесват целулоза, n-метилморфолин-n-оксид и вода, като сместа се подлага на скоростен градиент от 400 до 3000 сек-1, като се спазват следните условия: сцел > 0,3469-1,695 сн20 и сцел 0,58-2,23 сн2о. 4 претенции
