Tetrachloroethane is an important raw material for chemical production, which is widely used in various fields. This article will detail the properties and uses of tetrachloroethane.

1. the nature of tetrachloroethane

1. physical properties

tetrachloroethane is a colorless transparent, volatile liquid, pungent odor. Its boiling point is 146.5 ℃, melting point is -43.8 ℃, density is 1.602g/cm³, insoluble in water, soluble in organic solvents.

2.
of chemical properties The chemical properties of tetrachloroethane
is relatively stable, but it is easy to decompose and chlorination under high temperature, light and acidic conditions. It can react with alkali metals, alkaline earth metals, aluminum, magnesium and other metals to generate the corresponding metal organic compounds. In addition, tetrachloroethane can also occur with many organic substitution, addition reaction.

2. the use of tetrachloroethane

1. Production of refrigerant

tetrachloroethane can be used as a refrigerant, its cooling effect is similar to Freon, but the price is lower. It is widely used in air conditioners, refrigerators and other refrigeration equipment.

2. Production solvent

Tetrachloroethane is an excellent solvent, which can be used to dissolve rubber, resin, paint and other substances. It can also be used as a solvent for the extraction of vegetable oils.

3. production of pesticides

tetrachloroethane can be used for the production of pesticides, such as pesticides, fungicides. It can also be used as an intermediate for pesticides to synthesize other pesticides.

4. Production of other chemicals

Tetrachloroethane can also be used to produce other chemicals, such as vinyl chloride, tetrachloroethylene, etc. These chemicals are widely used in plastics, synthetic fibers, synthetic rubber and other fields.

In short, tetrachloroethane as an important chemical production raw materials, in various fields have a wide range of applications. It is necessary to pay attention to its toxicity and safety during use to avoid harm to the human body and the environment.
