Abstract

The article proposes a new method for producing cellulose nitrate esters by pretreatment of cellulose with low concentrated nitric acid. Optimal conditions for the esterifi- cation reaction have been developed. Some properties of mono- and di- and trisubstituted nitrates were studied: degree of substitution, solubility, degree of polymerization, IR spectra, X-ray diffraction patterns are given.
