The solubility of nitrocellulose depends on the nitrogen content and to a lesser extent on viscosity. All industrial nitrocellulose grades with nitrogen content of 10.7 to 12.2% are soluble in esters, ketones, glycol ethers (active solvents) or in suitably formulated mixtures of these with hydrocarbons (diluents) and/ or alcohols of low molecular weight. Low nitrogen grades are used where high alcohol or spirit solubility is desired.
