Diethylene glycol dinitrate

Chemical compound From Wikipedia, the free encyclopedia

Remove ads

Diethylene glycol dinitrate (DEGDN) is an explosive nitrated alcohol ester with the formula C4H8N2O7. It is commonly used as a plasticizer in propellant or explosive formulations.[1] While chemically similar to numerous other high explosives, pure diethylene glycol dinitrate is difficult to ignite. Ignition typically requires localized heating to the decomposition point unless the DEGDN is first atomized. It is sensitive to detonation by impact but not due to friction.[2]

Preparation and uses

Diethylene glycol dinitrate can be made by nitration of diethylene glycol with nitric acid in presence of a dehydrating agent like concentrated sulfuric acid.[3]

Toxicity

If ingested, like nitroglycerine, it rapidly causes vasodilation through the release of nitric oxide, a physiological signaling molecule that relaxes vascular smooth muscle which leads to a rapid loss in blood pressure. Other acute effects include convulsions and loss of consciousness.[4] Its median lethal dose (LD50) is 650 mg/kg in guinea pigs.[5]

Uses

DEGDN can be mixed with nitrocellulose or nitroglycol to form a colloid, which is used in smokeless powder for artillery and rocket propellant.[1] During World War II, the Kriegsmarine frequently used this mixture in their artillery.[6]

Triethylene glycol dinitrate, diethylene glycol dinitrate, and trimethylolethane trinitrate can be used as less-sensitive as replacements for nitroglycerin in propellants.[1][7]
