What Is Trichloroethylene TCE Chemical Used For in Industry? (CAS No:79-01-6)

CAS No: 79-01-6 Trichloroethylene (TCE) is a non-flammable, colorless chlorinated hydrocarbon with a characteristically sweet, chloroform-like scent. For nearly a century, its exceptional ability to dissolve a wide range of organic materials-particularly oils, greases, waxes, and tars-has made it an invaluable tool in heavy industry. Its high stability and low flammability made it a safer alternative to more volatile solvents of its time.

What Is Trichloroethylene (CAS 79-01-6)?

High purity Trichloroethylene (TCE) is an organic compound with the chemical formula C₂HCl₃. It is a colorless organic solvent with a mildly sweet odor. It belongs to the halocarbon group, characterized by its non-flammable nature and rapid evaporation.

CAS No: 79-01-6 Trichloroethylene also known as Ethylene trichloride; 1,1,2-Trichloroethylene; Triclene; TCE solvent.

Key Characteristics:

• Strong dissolving power
• Moderate evaporation rate
• Non-flammable under normal conditions
• High density and stability

These features make TCE chemical a preferred solvent in industrial environments.

What Is Trichloroethylene TCE Chemical Used For in Industry? (CAS No:79-01-6)

1. Degreasing and Cleaning of Industrial Metals

Trichloroethylene (CAS No: 79-01-6) is a core solvent in metal processing. It is widely used to remove stubborn grease, oil stains, and contaminants from metal equipment, machine parts, and precision components. TCE solvent is non-flammable and has a high boiling point, allowing for steam degreasing and ensuring thorough cleaning and safety even at high temperatures.

2. Raw Material for Refrigerant Production

Trichloroethylene (CAS No: 79-01-6) is an essential chemical raw material in the production of hydrofluorocarbon (HFC) refrigerants. It is used in the synthesis and production of refrigerants for HVAC systems, refrigeration equipment, and related industrial cooling applications.

3. Extraction Solvent in the Textile Industry

In textile processing, Solvent TCE is a specialized extraction solvent. It effectively dissolves and removes natural impurities from fabrics such as cotton and wool.

4. Chemical Intermediate in Pharmaceutical Production

Trichloroethylene liquid is an important chemical intermediate, primarily used in the pharmaceutical industry. It participates in chemical synthesis reactions for the production and preparation of pharmaceutical ingredients and compounds.

5. Additives

In addition to industrial applications, TCE is also added as a functional ingredient to many everyday and chemical products:

• Typewriter correction fluid
• Adhesives and lubricants
• Fabric stain removers
• Paint removers and thinners
• Carpet cleaners

Safety and Regulatory Considerations

Although highly effective, TCE must be handled carefully.

1. Potential health risks with long-term exposure
2. Environmental contamination (especially groundwater)
3. Increasing global regulations

Regulatory Overview:

Restricted under EU REACH

Controlled usage in the US and other regions

Many industries are gradually exploring safer alternatives.
