Ethylene glycol dinitrate, IUPAC name 1,2-dinitroxyethane, also known as nitroglycol or EGDN, is a pale yellow, syrupy, explosive liquid. In the series of alkyl nitrates it is among those which have a 1:1 rato of nitroxy groups per carbon atom, and also exhibits a perfect oxygen balance.
Contents
Properties
Explosive
Thanks to its perfect oxygen balance, EGDN is one of the strongest explosives known, with a lead block test value of 650 cm3 (10% higher than NG). It is more sensitive to initiation but can also detonate incompletely with low velocity. The reported detonation velocity is around 7800 m/s.
Physical
Its properties are very similar to nitroglycerin. It is however less viscous, less dense and more volatile. The freezing point is -22 °C, and it has therefore been used for dynamites in cold climates.
Preparation
EGDN can be prepared by nitrating ethylene glycol under careful monitoring.
Handling
Safety
Like nitroglycerin, EGDN is highly explosive, although somewhat less sensitive to impact. One disadvantage EGDN has against NG is that EGDN is more volatile. This makes a person working with it more susceptible to its vasodilation effects, which is where the nitro group in the nitrated alcohol causes the body to widen blood vessels, resulting in phenomenal headaches.
Storage
Never store EGDN!
Disposal
