EGDN Chemical Properties,Uses,Production
Chemical Properties
Ethylene glycol dinitrate is a colorless to yellow, oily, odorless liquid. An explosive ingredient (60%80%) in dynamite along with nitroglycerine (40%20%). It may be detonated by mechanical shock, heat, or spontaneous chemical reaction
Uses
Explosive for mining and fuel industries. Additive to dynamite. Detection of hidden bombs by analysis of ambient air for EGDN.
Definition
A freezing-point depressant for nitroglycerine.
General Description
Colorless to yellow, oily odorless liquid with a sweetish taste. Mp: -22°C; bp: explodes at 114°C. Density: 1.49 g cm-3. Soluble in water (23.3 g/L H2O) at 25°C). Very soluble in ethanol and in ether. Used as an explosive ingredient in dynamite along with nitroglycerine. Toxic; can penetrate the skin.
Reactivity Profile
EGDN is explosive. Acts as a strong oxidizing agent. Heating to 114°C or above may cause a violent combustion or explosion producing toxic fumes (nitrogen oxides). May also decompose explosively from shock, friction or from a build-up of electrostatic charge that sparks suddenly to ground. Can begin a vigorous reaction that culminates in an explosion if mixed with reducing agents including hydrides, sulfides, and nitrides and numerous ordinary combustible materials. Reacts violently with Al, BP, cyanides, esters, PN2H, P, NaCN, SnCl2, sodium hypophosphite, and thiocyanates. Reacts with acids and with alkalis, including ammonia and amines. Must be stored in a cool, ventilated place, away from acute fire hazards and easily oxidized materials (Sax and Lewis, 1987 p.664).
Hazard
Toxic by skin absorption.
Health Hazard
EGDN causes vasodilation and cardiac effects.
Safety Profile
Can cause lowered blood pressure leading to headache, dizziness, and weakness. Used as an explosive. When heated to decomposition it emits toxic fumes of NOx. See also NITRATES.
Potential Exposure
An explosive ingredient (60%80%) in dynamite along with nitroglycerine (40%20%). Although ethylene glycol dinitrate is an explosive in itself, it is primarily used to lower the freezing/melting point of nitroglycerin; together these compounds are the major constituents of commercial dynamite, cordite, and blastine gelatin. Occupational exposure generally involves a mixture of the two compounds. Ethylene glycol dinitrate is 160 times more volatile than nitroglycerin.
Shipping
UN0473 Substances, explosive, n.o.s., Hazard Class: 1.1 A; Labels:1.1A-Explosive (with a mass explosion, hazard); A-Substances which are expected to mass detonate very soon after fire reaches them, Technical Name Required
Incompatibilities
Unstable; highly explosive. Heating may cause violent combustion or explosion producing toxic fumes (nitrogen oxides). May explosively detonate violently from heat above 200℃, mechanical shock, friction, impact or concussion. Not compatible with strong acids and alkalies
