Detailed Product Description:
A colorless non-flammable liquid with ether-like odor. Miscible in most
oils, alcohol, and ether. Non-soluble in water. Commonly used as a dry
cleaning solvent for clothing or for vapor-degreasing of metal parts and
precision instruments.
Grade/Purity:
This is electronics grade material with minimum purity of 99.5%.
Background:
Tetrachloroethylene, most commonly known as perchloroethylene, perc,
and PCE, is a chlorinated hydrocarbon. It has a sweet odor detectable
by most people at a concentration of 1 part per million (1 ppm).
Production
Most tetrachloroethylene is produced by high temperature chlorinolysis
of light hydrocarbons. The method is related to Faraday's discovery since
hexachloroethane is generated and thermally decomposes. Side products
include carbon tetrachloride, hydrogen chloride, and hexachlorobutadiene.
Applications:
Most tetrachloroethylene is consumed as a solvent used in dry cleaning.
It is desirable because it dissolves many organic materials, it is volatile,
highly stable, and nonflammable. Usually as a mixture with other
chlorocarbons, it is used to degrease metal parts in the automotive and
other metalworking industries. It appears in a few consumer products
including paint strippers and spot removers. It is also used as a solvent
for proton NMR spectroscopy.
Precautions:
Like many chlorinated hydrocarbons, perc is a central nervous system
depressant, and inhaling its vapors (particularly in closed, poorly-ventilated
areas) can cause dizziness, headache, sleepiness, confusion, nausea, difficulty
in speaking and walking, unconsciousness, and even death.
After repeated or extended skin contact, it may dissolve fats from the skin,
resulting in severe skin irritation in work environments where people have
been exposed to high concentrations.
The International Agency for Research on Cancer has classified perc as a
Group 2A carcinogen, which means that it expected to be carcinogenic to humans.
Irritant to eyes, nose and skin. TLV = 50ppm
