Trichloroethylene CAS:79-01-6

Trichloroethylene (TCE) is a compound formed when three hydrogen atoms in an ethylene molecule are replaced by chlorine. It is sparingly soluble in water but soluble in ethanol, ether, etc. Trichloroethylene is a flammable liquid and poses a fire and explosion hazard when exposed to open flames or high heat. Trichloroethylene has been used as an analgesic and metal degreasing agent, and can also be used as an extractant, bactericide, refrigerant, and dry cleaning agent. Prolonged exposure can cause trigeminal neuralgia and other conditions.

1. Metalworking

Trichloroethylene is often used for degreasing and cleaning in the metalworking industry. During the manufacturing process of mechanical parts, grease, oil or other impurities are often attached to metal surfaces. Trichloroethylene effectively dissolves these organics, leaving the metal surface clean for subsequent processing or coating. Compared with other solvents such as acetone or gasoline, trichloroethylene is moderately volatile and less prone to rapid evaporation, which helps to maintain a longer duration of action during the cleaning process and reduces the need for repeat operations. However, it is important to note that trichloroethylene is highly toxic and requires strict adherence to safety regulations when used, while acetone, although less toxic, is more flammable and requires higher storage and transportation requirements.

2.Chemical production

In the chemical industry, trichloroethylene is used as a solvent or extractant in many chemical reactions. For example, in some synthesis processes, it helps to dissolve raw materials or intermediates to facilitate the reaction. Trichloroethylene is less flammable than aromatic hydrocarbon solvents such as benzene or toluene, which may make it safer in certain high-temperature or high-pressure environments. However, benzene solvents are more soluble in some cases, but are also more toxic and prone to environmental contamination. Trichloroethylene is chemically more stable, but prolonged exposure may cause corrosion of equipment and requires regular maintenance.

3. Textile industry

Trichloroethylene is also used in the textile industry. In textile processing, it is used as a stain remover or degreaser to treat natural fibers such as cotton and wool to remove wax and oil stains from their surfaces. This helps to improve the uniformity and firmness of dyeing, resulting in a final product with brighter colors and a softer texture. For example, in the production of denim, trichloroethylene is used at the pretreatment stage to help remove natural impurities from cotton fibers, laying the foundation for subsequent bleaching and dyeing. Trichloroethylene is also used in the dry-cleaning industry as a solvent to clean clothes, and is particularly suited to removing oily stains, although conditions of use need to be strictly controlled to avoid residues.
