Nitrocellulose Manufacture Continuous Methods

Continuous Methods for Manufacturing Nitrocellulose. Several methods are known, of which the Dietzsch process developed during WWII in Germany is briefly described here under Combustible and Consumable Cartridge Cases. This method combines vapor-phase and liquid-phase nitration processes. The Japanese used during WWII a continuous liquid-phase method of nitration of paper pulp, which was in the form of a sheet...

Treatment in autoclaves was also used in earlier years to reduce the viscosity of collodion cotton intended for the manufacture of varnishes. For the same purpose, a water slurry of nitrocellulose may be boiled under hydrostatic pressure in tubes, as a continuous process. These methods are discussed in detail in the chapter devoted to the manufacture of collodion cotton for varnish production.
