Nitrocellulose pentaerythritol trinitrate

J.Reinhart et al of NOL, "Nitrasol Propellants -Composite Propellant Formulations Based on a Plastisol-Nitrocellulose-Pentaerythritol Trinitrate Binder (U), Bull of the 14th Meeting of the Joint Army-Navy-Air Force Solid Propellant Group, Johns Hopkins University, Silver Spring, Md(1958)(Conf)(Not used as a source of info) 1)... 

Pentaerythritol trinitrate can be determined in nitrocellulose propellants containing, as major constituents, nitroglycerine, nitrocellulose, 2-nitrodiphenylamine and dibutylphthalate. As nitrocellulose and dibutylphthalate do not interfere, but the waves of the other three compounds coincide, it was necessary to use a special technique. The sample of the propellant is first dissolved in acetone. An aliquot is added to a supporting electrolyte, so that the resulting solution consists of 0-25 m tetramethylammonium chloride, 70 per cent ethanol, 10 per cent acetone and 20 per cent...
