Tetrachloroethylene is a non flammable liquid at room temperature. It is easy to evaporate into the air, with a pungent and sweet smell. Most tetrachloroethylene will enter water or soil, and then evaporate into air. Microorganisms can decompose some soil or soil be launched Tetrachloroethylene in. In the air, tetrachloroethylene will be decomposed into other chemicals by sunlight, or returned to soil and water through rainfall.
Appearance and property: colorless liquid.
Molecular structure data:
1. Molar refractive index: 30.45
2. Molar volume (ml/mol): 100.3
3. Isotonic specific volume (90.2K): 245.0
4. Surface tension (dyne/cm): 35.6
5. Polarization rate (10-24cm3): 12.07
chemical property
1. Generally, it will not burn, but it can still burn when exposed to open fire and high temperature for a long time.
2. Pure tetrachloroethylene will not be oxidized in the dark in the air, but will be gradually oxidized under the action of ultraviolet light.
