The location of a substituent groups in partially nitrated and in partially xanthated celluloses.

By Errol. L. Falconer


During a study of the degradative action of pyridine on cellulose trinitrate, G.H. Segall discovered that a solution of hydroxylamine in pyridine removed one nitrate group per anhydroglucose unit from the trinitrate. The selectivity of this reaction was demonstrated, and a possible specificity for one of the two secondary nitrate groups in the anhydroglucose units was suggested. The unusual stability of Segall's "dinitrate" to alkalies permitted methylation to a "mono-0-methyl dinitrate" with dimethyl sulphate and sodium hydroxide
