Physical Properties. The physical properties of trichloroethylene are as given below: It exists as a colorless volatile liquid having a sweet odor like chloroform. It has a molecular weight of 131.38 g/mol. It has a density of \ (1.46 g/cm^3\) at 20 °C. It has a melting point of −84.8 °C (−120.6 °F; 188.3 K).

TCE is carcinogenic to humans by all routes of exposure and poses a potential human health hazard for noncancer toxicity to the nervous system, kidneys, liver, immune system, male reproductive system, and the developing embryo/fetus.

Uses [ edit] Trichloroethylene is an effective solvent for a variety of organic materials. When it was first widely produced in the 1920s, trichloroethylene's major use was to extract vegetable oils from plant materials such as soy, coconut, and palm.
