The lyocell process: Cellulose solutions in N-Methylmorpholine-N-oxide (NMMO) - degradation processes and stabilizers
Abstract
Homolytic (radical) reactions in the system cellulose / N-methylmorpholine-N-oxide (NMMO, 1) involve a primary, nitrogen-centered cation radical (2), and two secondary, carbon-centered radical species (3, 4). Radical formation &om NMMO is strongly promoted by transition metal ions.
