The stability properties of dextran nitrates, prepared by nitric acid alone and by mixed acids, have been determined and their stabilisation has been also attempted. While the stability of the crude dextran nitrates varied appreciably according to the method of preparation, the stabilised forms possessed closely similar stability properties. The stability of the nitrated α‐D‐glucose polymeric carbohydrate dextran, as previously reported in the case of other α‐D‐glucose polymeric carbohydrate nitrates, is now apparently found much lower than that of the nitrated β‐D‐glucose polymeric carbohydrate cellulose.
