(EC No 203-459-7) Uses
(EC No 203-459-7) is a building block in the production of pharmaceuticals, biocides and plasticizers. It is also used for manufacture of thiodiglycol. It is a solvent for cellulose acetate and ethyl cellulose, textile printing dyes, extraction of pine lignin, in dewaxing, refining of rosin, and the cleaning of machines.
Several dyes are prepared by the alkylation of aniline derivatives with chloroethanol.
(EC No 203-459-7) Production
(EC No 203-459-7) is produced by treating ethylene with hypochlorous acid:
CH2=CH2 + HOCl → HOCH2CH2Cl

(EC No 203-459-7) Safety Profile
A poison by ingestion, inhalation, skin contact, intraperitoneal, intravenous, and subcutaneous routes. Moderately toxic to humans by inhalation. It can affect the nervous system, liver, spleen, and lungs. An experimental teratogen. Mutation data reported. A severe eye and mild skin irritant. Flammable liquid when exposed to heat, flame, or oxidizers. To fight fire, use alcohol foam, CO2, dry chemical. Violent reaction with chlorosulfonic acid, ethylene diamine, sodium hydroxide. Reacts with water or steam to produce toxic and corrosive fumes. Potentially violent reaction with oxidizing materials. When heated to decomposition it emits highly toxic fumes of Cl? and phosgene. See also CHLORINATED HYDROCARBONS, ALIPHATIC.
Like most organochlorine compounds, (EC No 203-459-7) combusts to yield hydrogen chloride and phosgene.
