Uses
Epichlorohydrin (CAS NO.106-89-8) is a highly reactive compound,it is often used in the production of plastics,glycerol, and elastomers. Epichlorohydrin is a versatile precursor in the synthesis of many organic compounds. Epichlorohydrin is also used in water purification and paper reinforcement,such as in the food industry to manufacture coffee filters,tea bags, and sausage/salami casings.
Production
Epichlorohydrin can be manufactured from allyl chloride in two steps:

Safety Profile
Confirmed carcinogen with experimental carcinogenic data. Poison by ingestion, skin contact, intravenous, and intraperitoneal routes. Moderately toxic by inhalation. An experimental teratogen. Other experimental reproductive effects. Human systemic effects by inhalation: respiratory, nose, and eyes. Human mutation data reported. A skin and eye irritant. A sensitizer. Flammable liquid when exposed to heat or flame. Explosive reaction with aniline. Reaction with trichloroethylene forms the explosive dichloroacetylene. Ignition on contact with potassium tert-butoxide. Violent reaction with sulfuric acid or isopropylamine. Exothermic polymerization on contact with strong acids, caustic alkalies, aluminum, aluminum chloride, iron(III) chloride, or zinc. When heated to decomposition it emits toxic fumes of Cl−.
