Tetrachloroethylene Chemical Properties,Uses,Production
Description
Perchloroethylene (Tetrachloroethylene) is a colourless liquid with a slightly ethereal odour. It is marginally soluble in water and soluble in most organic solvents.Perchloroethylene has a limited number of uses and applications. It is used as intermediate, as dry cleaning agent in the industrial and professional sector, as surface cleaning agent in industrial settings, as heat transfer medium in industrial settings, and in film cleaning and copying by professionals. It is also used as a chemical intermediate in the production of fluorinated compounds and in industrial surface cleaning metal degreasing. Occupational exposure to perchloroethylene is possible in the manufacturing facilities or the industrial facilities where it is used as an intermediate.
Chemical Properties
Tetrachloroethylene is a clear, colorless, nonflammable liquid with a characteristic odor. The odor is noticeable @ 47 ppm, though after a short period it may become inconspicuous, thereby becoming an unreliable warning signal. The Odor Threshold is variously given as 5 ppm to 6.17 (3M).
Uses
Tetrachloroethylene is used as a solvent, indrycleaning, and in metal degreasing.Tetrachloroethylene is a common industrial solvent that is often found as a contaminant in groundwater. Tetrachloroethylene is also a suspected carcinogen to humans and is difficult to degrade biologically as it has no natural source. This compound is a contaminant of emerging concern (CECs).
Production Methods
Tetrachloroethylene (PCE) was first prepared in 1821 and commercial production in the United States began in 1925. Several commercial grades are available that differ in the amount and type of added stabilizers (e.g., amines, phenols, and epoxides).
The industrial processes for production of tetrachloroethylene include threetechnical routes:
(1) chlorination of trichloroethylene and followed by dehydrochlorination.
(2) oxychlorination of ethylene.
(3) chlorination andpyrolysis of light hydrocarbon.
In China, the chlorination of trichloroethylene and dehydrochlorination process is mainly used for production of tetrachloroethylene, while the other two processes are widely used in other countries.
Carcinogenicity
Tetrachloroethylene is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.
