Preparation of Ethylenediamine : this chemical is prepared by the reaction of ammonia and 1,2-dichloroethane . This reaction can give the mixture of ethylenediamine and the linear polyamines.
ClCH₂CH₂Cl + 4 NH₃ → H₂NCH₂CH₂NH₂ + 2 NH₄Cl

Uses of Ethylenediamine : this compound is mainly used for production of many chemicals. Here is a example.

This reaction will use the solvent water and AcOK / AcOH buffer, pH = 5. The yield is about 30%.

When you are using this chemical, please be cautious about it as the following:
A human poison by inhalation. Experimental poison by inhalation, intraperitoneal, subcutaneous, and intravenous routes. Moderately toxic by ingestion and skin contact. Experimental reproductive effects. Corrosive. A severe skin and eye irritant. An allergen and sensitizer. Mutation data reported. Flammable liquid when exposed to heat, flame, or oxidizers. Can react violently with acetic acid, acetic anhydride, acrolein, acrylic acid, acrylonitrile, allyl chloride, CS₂, chlorosulfonic acid, epichlorohydrin, ethylene chlorohydrin, HCl, mesityl oxide, HNO₃, oleum, AgClO₄, H₂SO₄, β-propiolactone, or vinyl acetate. To fight fire, use CO₂, dry chemical, alcohol foam. When heated to decomposition it emits toxic fumes of NO_x and NH₃.
