Trichloroethylene is an organic compound with the chemical formula C2HCl3. It is a compound formed by the substitution of three hydrogen atoms in the ethylene molecule by chlo rine. It is a colorless and transparent liquid, insoluble in water, soluble in ethanol and ether, and miscible. Most organic solvents, mainly used as solvents, can also be used for degreasing, freezing, pesticides, fragrances, rubber industry, washing fabrics, etc.
Trichloroethylene (IUPAC), CHClCCl2, is a stable, low-boiling, colorless liquid with a chloroform-like odor. It is not corrosive to the common metals even in the presence of moisture. It is slightly soluble in water and is nonflammable. It is toxic by inhalation, with a TLV of 50 ppm and an IDLH of 1000 ppm in air. The FDA has prohibited its use in foods, drugs, and cosmetics. The four-digit UN identification number is 1710. The NFPA 704 designation is health 2, flammability 1, and reactivity 0. Its primary uses are in metal degreasing, dry cleaning, as a refrigerant and fumigant, and for drying electronic parts.
