Abstract

Cellulose is nitrated by means of a liquid oxide of nitrogen, for example nitric acid, nitrogen trioxide or nitrogen pentoxide. An example is given of the nitration of cotton by means of liquid nitric oxide. Specification 358,436 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) refers also to the production of cellulose nitrate-acylates by the treatment of cellulose with liquid oxides of nitrogen in the presence of the anhydride of a fatty acid or of the anhydrides of two or more fatty acids of from 2 to 6 carbon atoms each. The acylation reactions may also be carried out with acyl chlorides, or with fatty acids and an impelling agent. Anhydrides mentioned are the anhydrides of acetic, butyric, propionic, and stearic acid. Examples are given of the production of the nitrate-acetate, nitrate-acetate-butyrate, nitrate-valerate-caproate, and nitrate-acetate-butyrate-valerate. This subject-matter does not appear in the Specification as accepted.
