The nitration of cellulose in technical mixed acids has been studied by X-ray photoelectron spectroscopy and 13 C nuclear magnetic resonance. The study was carried out in order to better our understanding of the nitration mechanism, and of the factors that control the extent of nitration achieved in these mixes. From this work two major conclusions can be drawn: (1) that the nitronium ion, NO~, is the important nitrating species of cellulose; and (2) contrary to previous arguments, fibre crystal structure does play an important role in determining the degree of substitution (DOS) achieved, but not as previously envisaged.
