Transport Information UN 1135 Appearance clear, colorless liquid.
Safety 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.

2-Chloroethanol Chemical Properties

MF: C2H5ClO
MW: 80.51
EINECS: 203-459-7
ETHYLENE CHLOROHYDRIN,it's melting point is about -63 °C ,boiling point is 129 °C(lit.),density is 1.201 g/mL at 25 °C(lit.).It is colorless liquid with a pleasant ether-like odor. It is miscible with water.

2-Chloroethanol Uses

ETHYLENE CHLOROHYDRIN 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.

2-Chloroethanol Production

ETHYLENE CHLOROHYDRIN is produced by treating ethylene with hypochlorous acid:
CH2=CH2 + HOCl → HOCH2CH2Cl
