    Three hydrogen atoms in trichloroethylene and ethylene molecules are replaced by chlorine.Insoluble in water, soluble in ethanol, ether and so on.Trichloroethylene is a flammable liquid, and the danger of fire explosion can be caused by open flame and high heat.Trichloroethylene has been used as an analgesic and a metal degreasing agent, which can be used as an extractant, fungicide and refrigerant, as well as dry cleaning agent for clothes.Prolonged exposure can cause symptoms such as trigeminal nerve paralysis.


   Excellent solvent, used as a metal surface treating agent, electroplating, pre-lacquer cleaner, metal degreasing agent and the extraction agent of fat, oil and paraffin.For organic synthesis, pesticide production.Trichloroethylene is used to produce tetrachloroethylene as a repellent.It is used for the production of hexachloroethane, which is used as the animal's insect repellant, to control ruminant liver disease and leech disease, clonococcidiasis and nematode disease.

Nature and stability


1. Chemical properties: trichloroethylene without stabilizers is gradually oxidized in the air to generate photogas, carbon monoxide and hydrogen chloride.

It is possible to generate a small number of dimers (hexachlorene).

The reaction is conducted according to the free radical process, and the light and heating obviously promote the reaction.

When water is present, dichloroacetyl chloride is decomposed into dichloroacetic acid and hydrogen chloride.

The acid that is produced is corrosive to metals.

Therefore, the trichloroethylene used in the industry is usually used in trace stabilizers such as phenols (hydroquinones), amines or alcohols.

Add stabilizer of trichloroethylene in the presence of air, water and light, even if heated to 130 ℃ and general metal material is not used in industry.

2. Trichloroethylene steam heated to above 700 ℃, decomposition produce dichloroethylene, tetrachloroethylene, carbon tetrachloride, chloroform, and a mixture of methyl chloride.

When the vapor of trichloroethylene is strongly associated with air, it is completely oxidized to produce carbon dioxide, hydrogen chloride, carbon monoxide and phosgene.

In the presence of copper salt, trichloroethylene heated to 175 ℃ under pressure, with alkali metal or alkaline earth metal hydroxide aqueous solution or suspension reaction, generate hydroxyacetic acid salt.

When cold is not reacted with hydrochloric acid and nitric acid, the reaction of heat with concentrated nitric acid is completely decomposed, and the control reaction conditions can be obtained by trichloro nitro methane and monochlorodinitro-methane.

Under the effect of aluminium trichloride catalyst, 30 ~ 50 ℃ react with hydrogen chloride, say - tetrachloroethane generated.

In the presence of caustic soda, dehydrochlorination reaction produces dichloroacetylene, and dichloroacetylene is spontaneously ignited and exploded in the air.

Sodium carbonate and liquid ammonia don't react with trichloroethylene in normal conditions.

The metal aluminum, especially the powdered aluminium, can cause the breakdown of trichloroethylene, which contains no stabilizers, and when the hydrogen chloride is produced, a strong explosive decomposition or carbonization occurs.

The reaction was made of aluminum chloride, and aluminum chloride was used as the Friedel Crafts catalyst to induce the condensation reaction of trichloroethylene, and the production of pentachlorobutadiene was further reduced to resin and tar.

In the presence of aluminium chloride, trichloroethylene and chloroform react, yielding 1, 1, 1, 2, 3, 3-6 chloropropane.

The reaction with carbon tetrachloride was 1, 1, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3-7.

In peroxide, such as the presence of benzoyl peroxide, pressurized heating to 150 ~ 200 ℃, trichloroethylene dimer and trimer.

In the catalysis of ferric chloride, chloroethane and hexachloroethane are produced.
