Definition - What does Chlorinated Solvent mean?
This is a chemical compound that consists of one or two carbon atoms and at least one chlorine atom joined by covalent bonds.
It is used in commercial (aerospace, military and metalworking) and domestic applications such as paint thinners; thinning or mixing host in solutions, resins, degreasers, pesticides and chemical intermediates; and manufacturing and industrial cleaning solutions such as dry cleaning. The chlorine structure in this compound gives it the ability to absorb organic materials.
Corrosionpedia explains Chlorinated Solvent
Some of the commonly known chlorinated solvents include:
- Dichloromethane (DCM)
- Vinyl chloride (VC)
- Dichloroethene (DCE)
- Tetrachloroethene (PCE)
- 1, 1, 1 - Trichloroethane (TCA)
- Trichloroethene (TCE)
- Trichloroethylene (TCE)
- Methylene chloride or chloromethane (MC)
These relatively soluble solvents contain at least one atom of chlorine and one or two atoms of carbon covalently bonded; this leads to structural variety and divergence in chemical properties, making them have multiple applications. They are known to be volatile and less dense than water. Their use as a cleaning agent makes them a common soil and groundwater contaminant. They have a low viscosity and are chemically stable under typical aerobic conditions.
In health, they pose as risk and are classified as actual or potential cancer-causing compounds. In air and water surfaces, they disintegrate sequentially into other chlorinated solvents. The solvent can dissolve in groundwater and soil pore water. Hence, its degradation is by biochemical and abiotic reactions: oxidation, substitution, dehydrohalogenation and reduction.
