89035. Picatinny arsenal, Dover, New Jersey. 1990. – 18 p.It has been known for many years that nitrocellulose (NC) and nitroglycerin (NG) are not stable and decompose. However, very little is known about the decomposition process. It was found empirically that the addition of certain compounds apparently slowed the decomposition process or at least hindered a catastrophic explosion. This hindering of the explosive process occurs by the removal of NO2 by chemical reaction with the additional compounds or stabilizers as they are called. It seems apparent that diffusion must occur in these materials for the stabilizer to be able to do its work. Yet little or nothing is known about diffusion in NC or NC/NG base propellants. A general discussion of diffusion is followed by a discussion of an explicit model for stabilizer reaction with NO2 via diffusion of the latter.Content:
