Ethylenediamine, abbreviated as EDA, with the chemical formula C2H8N2, CAS：107-15-3，is a typical fatty diamine. It is a colorless or slightly yellow oily or water like transparent liquid that produces smoke in the air, has an ammonia like odor, and is hygroscopic.
Molecular weight 60.10, melting point 8.5 ℃, spontaneous ignition point 385 ℃. Belonging to alkaline substances, it is easily soluble in water and ethanol, slightly soluble in ether, and insoluble in benzene unless absolutely dry. It can form azeotropic mixtures with water, n-butanol, and toluene.
Flammable when exposed to heat, open flames, or oxidants, with a moderate risk of combustion. Can be sterilized under high pressure or through filtration.
Ethylene diamine can be used in the manufacturing of fuels, rubber vulcanization accelerators, pharmaceuticals, solvents such as fibrin, emulsifiers, epoxy resin curing agents, and intermediates in the manufacturing of insulation paint coatings. Ethylene diamine can be absorbed through the digestive tract, respiratory tract, and skin. Steam has a strong irritant effect on the skin and nasal mucosa, while liquids have a corrosive and allergenic effect.
