| titleOfInvention | Method of synthesizing diglycerol tetranitrate, and solid rocket motor propellant containing the same |
| abstract | Diglyercol tetranitrate is an energetic nitrate ester plasticizer having nonfreezing point, making the nitrate ester plasticizer especially suited for use innsolid rocket motor propellants that are subjected to low temperature storage andnoperational environments, which can reach as low as -54°C in temperature. Innorder to avoid problems associated with fume-off that characterize thenconventional synthesis method of making diglycerol tetranitrate, synthesis isnperformed in a medium including a mixed acid phase and an inert organic phase.nThe mixed acid phase contains, as ingredients, at least one nitronium ion sourcenand at least one acid having sufficient strength to generate nitronium ions fromnthe nitronium ion source. The nitronium ions in the mixed acid nitratedndiglycerol to form diglycerol tetranitrate, which is then received into the organicnliquid. The organic liquid, which preferably is a chlorocarbon such asndichloromethane, is insoluble with diglycerol but soluble with diglycerolntetranitrate. The inert organic phase is then treated to neutralize any acidncontained in the inert organic phase, and the diglycerol tetranitrate is separatednfrom the inert organic phase. |
