Abstract : The patent concerns a continuous, pollution-free process for manufacture of nitrocellulose. It involves passing cellulose and nitric acid-magnesium nitrate nitrating agent through an attrition mill, separating the spent nitrating agent from the nitrocellulose, purifying the latter by countercurrent water wash, treating the wash liquors with an ion-exchange system to recover the magnesium and nitrate values therefrom, and recycling the latter and spent nitrating agent to the system. The invention provides an efficient, closed system which generates no waste products to pollute the environment.
