Abstract

When nitrating cellulose in a comparatively dense form as prepared, for example, in the form of strings or pellets by the processes of Specifications 322,998 and 323,019, [both in Class 2 (ii), Cellulose &c.], penetration of the nitration acids is facilitated by mixing with cellulose a substance that produces gas in contact with sulphuric acid, for example, alkali carbonate or bicarbonate, and calcium carbonate. Sodium bicarbonate may be introduced by employing this substance as an ingredient of the hardening solution used in the process of Specification 323,019. Specification 322,997, [Class 2 (ii), Cellulose &c.], also is referred to. The Provisional Specification refers to the use of oxalic acid for the above purpose.
