Specification
1.General Description :Colorless to yellow, oily odorless liquid with a sweetish taste. 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.
2.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 .
