Cuprammonium complexes

Dissolution of the cellulose in cuprammonium solution followed by acid coagulation of extruded fibre ( cuprammonium rayon —no longer of commercial importance). In this case the acid converts the cuprammonium complex back into cellulose.

Taking into consideration the nature of the complex compounds between nitrocotton and metals or metal oxides, Miles [15] suggested that they approach in chemical character the cuprammonium complexes of cellulose. 

Those projected angles between hydroxyl groups which are capable of forming cuprammonium complexes have been determined by investigating substances in which the location of the adjacent hydroxyls is fixed by ring systems, and is known.11...
