Trichloroethylene Vapor Degreasing Grade – Technical Specifications

Trichloroethylene (TCE) Vapor Degreasing Grade: Technical Specifications

Trichloroethylene, identified by CAS No. 79-01-6, is a chlorinated hydrocarbon solvent exhibiting high volatility and stability. This technical-grade TCE is specially formulated for vapor degreasing applications in precision cleaning.

Chemical and Physical Properties

TCE, with the molecular structure C2HCl3, exhibits a boiling point at 87.2°C (189°F) and a melting point of -73°C (-99.4°F). It has a density of 1.46 g/mL at 25°C (77°F), a vapor pressure of 58 mmHg at 20°C, and a solubility in water of 1.1 g/L at 25°C.

Technical Purity and Quality Control

Our technical grade TCE has a minimum purity of 99.5%, verified by GC-MS analysis. It contains less than 50 ppm of non-volatile residue and less than 10 ppm each of chlorinated by-products like dichloroethylene and vinyl chloride.

Applications in Precision Cleaning

This grade of TCE is optimized for vapor degreasing, offering high solvency for non-polar compounds. It is particularly effective in removing grease, oils, and other hydrophobic substances from metal parts and electronic assemblies in aerospace and automotive sectors.

Safety and Handling

Exposure controls must align with occupational safety standards. TCE vapor concentration in air should not exceed permissible exposure limits. Use in a well-ventilated area, and employ personal protective equipment like solvent-resistant gloves, safety goggles, and respirators as necessary.

Storage and Stability

Store in a cool, dry, and well-ventilated area in tightly sealed containers, away from sources of ignition and incompatible materials like oxidizing agents. The product has a shelf life of 5 years under optimal storage conditions.


The high-purity Trichloroethylene Vapor Degreasing Grade is engineered for critical cleaning processes where solvent quality and consistency are paramount. Adherence to strict handling and storage guidelines ensures safety and maintains the integrity of the solvent for industrial use.
