Trichloroethylene Structure
Answers
Answer:
The chemical compound trichloroethylene is a halocarbon commonly used as an industrial solvent. It is a clear, colourless non-flammable liquid with a chloroform-like sweet smell. It should not be confused with the similar 1,1,1-trichloroethane, which is commonly known as chlorothene. The IUPAC name is trichloroethene.
Explanation:
What is Trichloroethylene?
Trichloroethylene is a clear, colorless mobile liquid with an odour similar to ether with the chemical formula C2HCl3.
Trichloroethylene was first prepared in 1864. It is man-made and does not occur naturally in the environment. Trichloroethylene emissions can occur principally from three sources, production, transportation and consumption. It can also be released to the environment through evaporation from adhesive glues, paints, coatings and other chemicals and during their production. (this is enough)
