Trichloroethylene , also known as trichloroethene is an organic compound, a haloalkene with the chemical formula ClCHCCl2.
Trichloroethylene is unstable in the presence of a metal over prolonged exposure.
Trichloroethylene is a clear non-flammable liquid with a sweet smell. It melts at −73 °C and boils at 87.2 °C.
Trichloroethylene is sold by some chemical suppliers.
Trichloroethylene can be synthesized by chlorinating ethylene over a ferric chloride catalyst to produce 1,2-dichloroethane, which is heated to 400 °C with additional chlorine, to yield trichloroethylene.
- CH2=CH2 + Cl2 → ClCH2CH2Cl
- ClCH2CH2Cl + 2 Cl2 → ClCH=CCl2 + 3 HCl
- Extract caffeine
- Make chloroacetic acid
Trichloroethylene is toxic if inhaled in large quantities.
In closed bottles, in dark well ventilated areas, away from metals.
Can be neutralized with sodium hydroxide or destroyed with Fenton's reagent. Make sure you perform the neutralization outside, as small amounts of solvent will evaporate and may fill the surrounding air.
