Web2.13.1 Introduction. The nitro group is a versatile and useful functionality which can be readily introduced to organic molecules. Due to its strong electron-withdrawing nature, a proton at the α-position of the nitro group (pKa is approximately 10) is easily abstracted even by a weak base ( Scheme 1 ). WebCellulose nitrate is the polynitrate ester of cellu-lose. Modern manufacture involves steeping cotton linters or paper pulp in a mixture of con-centrated nitric and sulphuric acid at 20-400C [4].
