Trichloroethylene (TCE) is a versatile solvent with wide commercial applications, chiefly due to its physical properties. It has high solvent power, is nonflammable and is practically insoluble in water. It is chemically stable under operating conditions. All this contributes to its popularity as a cleaning agent.

The Low latent heat, low boiling point, low viscosity and high vapour density of TCE make it ideal for vapour degreasing of metal parts without problems of handling. TCE is rapidly replacing other cleaning processes such as emulsion, alkaline and steam cleaning.

TCE is a clear, almost colourless, volatile liquid with a characteristic odour. It is highly soluble in ether and alcohol and is miscible with most organic solvents while being practically insoluble in water.



ApplicationsMetal cleaning, finishing and vapour degresing:
Cold, ultrasonic and vapour degreasing of metal parts between fabrication steps and before finishing or assembly, surface preparation of metal parts for galvanising, anodising, electro plating, painting and bonding.

For quick removal of oils and waxes in dip coating of rust preventing formulations, the oil and grease covered parts are placed in an atmosphere of TCE vapour. The hot vapour condenses immediately on the cold metal surface, dissolving the oils and greases and flushing them. The work heats to the vapour temperature in minutes, leaving the work clean, dry and ready for further treatment.
Solvent extraction:
Extraction of vegetable oils, waxes, animal fats, caffeine, cocoa butter, essential oils, pharmaceuticals, for recovery of oils and grease from waste, rags and paper, turnings etc.
Chemical Processes:
In dehydration and purification of many chemicals, as a reactant for manufacture of various halohydrocarbons and other chemicals, as an additive for promoting polymerisation of monomers etc.
