Chloroethylenes are a group of organic compounds that contain both chlorine and ethylene in their chemical structure. The most common example is vinyl chloride, which is primarily used to produce polyvinyl chloride (PVC), a widely used plastic. These compounds are typically colorless gases or liquids with a sweet odor and are known for their industrial applications. Chloroethylenes can be produced through various chemical processes, including the chlorination of ethylene. While they are useful in manufacturing, some chloroethylenes are considered hazardous due to their potential health effects, including carcinogenic properties. Proper handling and regulation are essential to minimize risks associated with their use.
