Trichloroethylene (TCE), CAS 79-01-6, is a colorless, non-flammable chlorinated hydrocarbon used as a vapor-degreasing solvent for heavy-duty industrial cleaning. It is used in metal degreasing, electroplating cleaning and controlled extraction processes, and is subject to regulatory restrictions in several jurisdictions. Confirm the grade, inhibitor or stabilizer system, intended controlled use and documentation before ordering; COA, TDS and SDS are available on request.

Description: Trichloroethylene is a colorless, transparent liquid classified under UN Class 6.1 (toxic). It is produced mainly by the acetylene (calcium carbide) route or the ethylene route. It is an excellent solvent used mainly as an electronics and electroplating cleaning agent, metal surface degreaser, metal pre-paint cleaning solvent and battery-industry extractant. It is also used as an intermediate for selected pesticides and as an extraction solvent in caprolactam production. Note that trichloroethylene is insoluble in water; do not add water where a single-phase solvent is required.
FAQ - Technical & Supply Chain
-
Q:
Are Trichloroethylene, Trichloroethene and TCE the same solvent?
A: Yes. These names identify CAS 79-01-6, formula C₂HCl₃. The product name alone does not show whether the grade is stabilized for vapour degreasing or supplied for another controlled industrial process. State the CAS number, required inhibitor system and intended use. -
Q:
What is Trichloroethylene used for?
A: It is used mainly as an electronics and electroplating cleaning agent, metal surface degreaser, metal pre-paint cleaning solvent and battery-industry extractant, and in selected pesticide and caprolactam process extraction. Note that TCE is not water-soluble, so water should not be added where a single-phase solvent is required. -
Q:
Which specifications should be agreed for stabilized Trichloroethylene?
A: Confirm TCE assay, water, colour, density, acidity or alkalinity, nonvolatile residue, distillation range and inhibitor identity or performance with the methods. The inhibitor package must be compatible with the metals, operating temperature and solvent-recovery system. -
Q:
What regulatory and delivery information is needed before purchasing TCE?
A: State destination country, authorized industrial use, annual quantity, packaging, transport route and whether the process is closed and emission-controlled. TCE supply and use are restricted in several jurisdictions, so actual availability and compliance must be confirmed. -
Q:
What handling and safety points apply to Trichloroethylene?
A: Review flammability, ventilation, exposure limits, stabilizer handling and waste-disposal requirements. Use closed or emission-controlled equipment where required, and confirm container compatibility, grounding and local occupational-health controls.
