Description

Tetrachloroethylene is a clear, colorless, volatile, nonflammable liquid with an ethereal odor. Insoluble in water. Vapors heavier than air. Density approximately 13.5 lb/gal. Used as dry cleaning solvent, a degreasing solvent, a drying agent for metals, and in the manufacture of other chemicals. 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

Tetrachloroethylene, also known under the systematic name tetrachloroethene, or perchloroethylene ("perc" or "PERC"), and many other names, is a chlorocarbon with the formula Cl2C=CCl2. It is a colorless liquid widely used for dry cleaning of fabrics, hence it is sometimes called "dry-cleaning fluid." It has a sweet odor detectable by most people at a concentration of 1 part per million (1 ppm). Worldwide production was about one million metric tons in 1985.

Tetrachloroethylene Use and Manufacturing

Methods of Manufacturing

1. Ethylene method This method can be combined with trichlorethylene and tetrachlorethylene, divided into the following two methods. A) Direct chlorination of ethylene and chlorine in a solution containing FeCl3 in 1, 2-dichloroethane at 280-450 ° C to produce 1, 2-dichloroethane, further chlorinating to trichlorethylene and Tetrachlorethylene, after distillation, respectively, with NH3 neutralization, washing, drying, that was finished. B) Oxidation of ethylene and chlorine to 1, 2-dichloroethane, 1, 2-dichloroethane and chlorine, oxygen in the CuCl2 and KCl as the catalyst and 425 ℃, 138-207kPa conditions Oxychlorination reaction, the product by cooling, washing, drying and distillation, high purity products.
2. Hydrocarbon Oxidation The hydrocarbon mixture containing methane, ethane, propane, propylene and the like is chlorinated at 50-500 ° C to obtain a mixture of chlorinated hydrocarbons and separated into various products after distillation.
3. Acetylene acetylene and chlorine heating chlorination to generate 1, 1, 2, 2-tetrachloroethane, hydrochloric acid removal of hydrogen chloride with trichlorethylene, and then chlorinated to produce pentachloroethane, and then off with alkali Hydrogen chloride is tetrachlorethylene. Due to acetylene price Ang, has gradually replaced by ethylene and other methods.
4. Preparation of acetylene chloride after the formation of tetrachloroethane, alkali removal of HCl after the removal of trichlorethylene, and then chlorination has become pentachloroethane, and then remove the HCl with calcium hydroxide to become tetrachlorethylene. For the preparation of pure tetrachlorethylene, nitrogen can be used as the carrier gas, and the crude product was injected onto a preparative gas chromatograph equipped with a fixed phase column of SE30 / white diatomaceous earth support, and its main peak component was separated and then charged into a glass ampoule Bottle seal can be.
5. Degradation of pentachloroethane with lime milk.

Uses

Tetrachloroethylene (PCE) is also known as perchloroethylene, tetrachloroethene, and 1,1,2,2- tetrachloroethene and is also commonly abbreviated to PER or PERC. Tetrachloroethylene is a volatile, chlorinated organic hydrocarbon that is widely used as a solvent in the dry-cleaning and textile-processing industries and as an agent for degreasing metal parts. It is an environmental contaminant that has been detected in the air, groundwater, surface waters, and soil (NRC, 2010). Tetrachloroethylene
