1,1-Dichloroethane is used in the manufacture of high-vacuum resistant rubber and for extraction of temperature-sensitive substances. 1,2 Dichloroethane, commonly known as EDC, is a clear, colorless, oily, synthetic flammable liquid chlorinated hydrocarbon. More than 90 percent of the world’s production of vinyl chloride monomer (VCM) uses EDC.
1,4-Dichlorobenzene, also called para-dichlorobenzene, is used to produce other chemicals such as polyphenylene sulfide (PPS) resin, a high-performance thermoplastic. 1,2-Dichlorobenzene, also known as ortho-dichlorobenzene, is mainly used as a raw material in the synthesis of agricultural chemicals.
1,1,2-Trichloroethane is used in the synthesis of 1,1-dichloroethylene (vinylidene chloride), which is used in semiconductor manufacture. 1,2-Dichloropropane is obtained as a byproduct of the production of epichlorohydrin, which is produced on a large scale. It is used in the production of the solvent perchloroethylene and other chlorinated chemicals.
Consumer exposure to chlorinated solvents is not typical. However, in industrial settings, workers can be exposed to chlorinated solvents through inhalation and skin contact. Short-term side effects to these sorts of exposure may include dizziness and fatigue.
Uses & Benefits
Chlorinated solvents are chemicals primarily used as raw materials in the production of other commercial products. They may be produced as byproducts or intermediates in the synthesis of other chlorinated materials.
1,2-Dichloropropane was used as a soil fumigant and as an industrial solvent. 1,1,2-Trichloroethane is used to produce high vacuum resistant rubber. The U.S. Forest Service used 1,2-Dichlorobenzene to fight bark beetle outbreaks. 1,4-Dichlorobenzene also has been used as a deodorizer and as a fumigant to help control moths, mold and mildew.
Occupational exposure to chlorinated solvents can occur through inhalation or skin contact. The National Institute for Occupational Safety and Health offers resources on managing chemical safety in the workplace.
