Ethylenediamine (EDA for short), chemical formula C2H8N2, is a typical aliphatic diamine, which is colorless or yellowish oily or water-like transparent liquid, produces smoke in the air, has an odor similar to ammonia, and is hygroscopic. Molecular weight 60.10, melting point 8.5 ℃, self-ignition point 385 ℃. It is an alkaline substance, easily soluble in water and ethanol, slightly soluble in ether, insoluble in benzene unless absolutely dry, and can form an azeotropic mixture with water, n-butanol and toluene. Flammable in case of heat, open fire and oxidant, with moderate combustion risk. It can be sterilized by high pressure or filtration.
Ethylenediamine can be used in the manufacture of fuels, rubber vulcanization accelerators, pharmaceuticals, solvents such as fibrin, emulsifiers, epoxy resin curing agents and intermediates for the manufacture of insulating paint coatings. Ethylenediamine can be absorbed through the digestive tract, respiratory tract and skin. Vapor has strong stimulation on skin and nasal mucosa, liquid has corrosive effect and sensitization effect.
Ethylenediamine can be prepared by reaction of ammonia and 1,2-dichloroethane. The mixture of ethylenediamine and other linear polyamines can be obtained after reaction.
