Glycoldinitrat (also Glykoldinitrat ) is a chemical compound selected from the group consisting of nitric acid ester.
Production and representation
Glycoldinitrat can be obtained by nitration with mixed acid of ethylene glycol. On an industrial scale, this is similar to carried out at nitroglycerin in continuous process.
Properties
Glycoldinitrat is a colorless, oily, slightly volatile liquid which is sparingly soluble in water and non-hygroscopic. In most organic solvents, it is readily soluble. The vapor pressure is relatively low at low temperature.
Glycoldinitrat is an explosive liquid that reacts to impact, friction, heat or other sources of ignition. Important explosion indicators are:
- Explosion heat 7294 kJ · kg -1.
- Detonation velocity 7300 m / s at a density of 1.48 g · cm -3
- Deflagration temperature: 217 ° C
- Lead block expansion cm3/10 620 g
- Impact sensitivity of 0.2 N · m
- Friction sensitivity to 353 N pin load no reaction
- Steel sleeve test limit diameter 24 mm (open sleeve )
Use
Glycoldinitrat is used as an explosive. Its effect is very similar to the nitroglycerin. It is often used in this mixture, as it decreases the freezing point for use in winter.
Safety
The pharmacological effects similar to those of nitroglycerin, with severe headaches occur in poisoning. The connection charged as all nitric acid esters intense circulation and is absorbed through the skin. The MAK value is 1.6 mg · m-3 and 0.25 ppm.
