Soldering terminology

Trade name of trichloroethene produced from acetylene and chlorine (CHC = CCl₂). In the past, it was most commonly used for degreasing electronic components before soldering, but this is now forbidden due to its chlorine content, which is a harmful substance. It is a colorless, non-flammable liquid with a melting point of -70°C, a boiling point of 87 °C and specific gravity of 1.459. Trichloroethylene is not soluble in water, but miscible with common organic solvents. It has a high solvency power and a much higher detergency than gasoline. It is also called D-triclene when used in the form of vapor. Waste water must be treated with activated carbon before disposal.
