二乙二醇二硝酸酯简介

Diethylene glycol dinitrate is a nitrated alcohol ester produced by the action of concentrated nitric acid, normally admixed with an excess of strong sulfuric acid as a dehydrating agent, upon diethylene glycol.
Diethylene glycol dinitrate is a colorless, odorless, viscous, oily liquid, with specific gravity 1.4092 at 0°C and 1.3846 at 20°C; freezing point −11.5°C under a standard atmosphere; the theoretical boiling point of approximately 197°C difficult to confirm as the compound begins to decompose and spontaneously inflames at or slightly below this temperature. Partial pressure is reported as 0.007mmHg (930mPa) at 22.4°C and 760mmHg (101kPa). It is readily miscible in most non-polar solvents, methanol, and cold acetic acid. Solubility in water (4.1g/L at 24°C) and ethanol is very low. While chemically similar to a number of powerful high explosives, pure diethylene glycol dinitrate is extremely hard to initiate and will not propagate a detonation wave. It inflames only with difficulty (requiring localized heating to decomposition point) unless first atomized, and burns placidly even in quantity.
Mixed with nitrocellulose and extruded under pressure, diethylene glycol dinitrate forms a tough colloid whose characteristics (good specific impulse, moderate burn rate and temperature, great resistance to accidental ignition and casual handling) make it well suited as a smokeless powder for artillery and a solid propellant for rocketry. It was widely used in this capacity during World War II (e.g., by the Kriegsmarine). It also found use as a "productive" desensitizer (one that contributes to the overall power of the explosion rather than having a neutral or negative effect) in nitroglycerine and nitroglycol-based explosives such as dynamite and blasting gelatin. It is also used as plasticizer for energetic materials.
If ingested, like nitroglycerine, it produces rapid vasodilation through the release of nitrogen monoxide, NO. Popularly-termed nitric oxide, NO is a physiological signaling molecule that relaxes smooth muscle. Consequently, diethylene glycol dinitrate has occasionally been used medically to relieve angina, substernal chest pain associated with impaired cardiac circulation. The rationale is that the concurrent headache it induces is somewhat less severe than other nitro compounds.
At present, interest in the chemical seems to be mostly historical: more potent perchlorate–metal mixtures have long since supplanted it as a solid propellant; safer explosives have replaced nitroglycerine, true dynamites (the term is often used generically, even by experienced field technicians, to refer to almost any explosive supplied in small, discrete packages) retaining only a few specialist uses. The medical application was never widespread, the standard nitroglycerine being faster acting and almost literally dirt cheap; oral nitrates in any case being only palliative, not an effective treatment.
Triethylene glycol dinitrate, diethylene glycol dinitrate, and trimethylolethane trinitrate are being considered as replacements for nitroglycerin in propellants.
