  • Processes for the production of free-flowing nitrocellulose
    Patent number: 4590019
    Abstract: Processes for the production of free-flowing, non-fibrous, alcohol-moistened nitrocellulose, characterized in that the water- or alcohol-moist nitrocellulose is softened with a solvent mixture of a nitrocellulose solvent and a lower aliphatic alcohol and water until the nitrocellulose fibers disappear, the alcohol-containing, liquid phase is decanted off from the two-phase mixture formed and the nitrocellulose-containing phase is processed into granulate using a screw extruder, the quantity of solvent mixture is used amounting to between 75 and 155% by weight, based on dry nitrocellulose, and the components of the mixture, NC-solvent:lower alcohol:water, being present in a ratio of 1:(0.2-4):(0.2-4).
