Dichloroethane, also known as ethylene dichloride, is a colorless, sweet-smelling liquid used primarily as a solvent and in the production of vinyl chloride, which is a key ingredient in making PVC (polyvinyl chloride). It is produced through the chlorination of ethane and is commonly found in industrial applications. This chemical is classified as a hazardous substance due to its potential health effects, including irritation of the skin and respiratory system. Prolonged exposure may lead to more serious health issues, making proper handling and safety measures essential in workplaces where it is used.
