Ethylene diamine ('''EDA''' or '''en'''), or '''1,2-diaminoethane''', is an Organic Compound from the Amines group. Its formula is 2-H2CH2-NH2. It is a strongly Alkaline , colorless to yellowish liquid, with amine odor, completely Miscible with water and soluble in Alcohol . Its melting point is 8.5 °C and boiling point 116 °C. Its CAS Reference Number is 107-15-3. (This is an extremely hazardous substance, as defined by Federal Regulatory Program lists. (scorecard.org)) THE ETHYLENAMINES Ethylene diamine is the diamine analogue of the dialcohol Ethylene Glycol . And as glycol is the first of a series of polyethylene glycols, EDA is the first member of polyethylene amines:
SYNTHESIS EDA is manufactured by reacting of Ammonia and 1,2-dichloroethane . The reaction yields the mixture of EDA and the linear polyamines. A simplified equation leading to EDA is presented (although EDA is more basic than NH3): ::ClCH2CH2Cl + 4 NH3 → H2NCH2CH2NH2 + 2 NH4Cl APPLICATIONS Ethylene diamine is used in the following applied and fundamental ways:
Ethylene diamine is used in large quantities for production of many industrial chemicals. It is very reactive, readily forms compounds with Carboxylic Acid s ( Amide s), Fatty Acid s ( Imidazoline ), Nitrile s ( Amidoamine s, Polyamide s, Imidazoline s), Alcohol s and Glycol s (alkylated or cyclic ethyleneamines), alkylhalides and arylhalides (substituted amines), Carbon Disulfide ( Thiocarbamate s), and forms water soluble salts with inorganic acids. Some products for which EDA is an important precursor are chelate agents like EDTA , the bleaching activator Tetra Acetyl Ethylene Diamine , chemicals for Color Photography developing, Lubricants for the Molding and processing of Plastic s, Fuel additives, Carbamate Fungicide s, Binders , Adhesive s, Fabric Softener s, Surfactant s, Curing agents for Epoxy s, and Dye s.
