C2H3ClO

C2H3ClO is the chemical formula for several different compounds, most notably vinyl chloride. Vinyl chloride is a synthetic organochlorine compound and a widely used industrial chemical. It is a colorless gas at room temperature with a faint sweet odor. It is a volatile substance and is flammable. Vinyl chloride is primarily used as a precursor to polyvinyl chloride (PVC), a common plastic. It is also used in the production of other polymers and copolymers.

The industrial production of vinyl chloride typically involves the dehydrochlorination of 1,2-dichloroethane. This process can be carried out thermally or catalytically. Alternatively, vinyl chloride can be produced by the direct chlorination of ethylene.

Vinyl chloride is a known human carcinogen. Exposure to vinyl chloride can occur through inhalation, ingestion, or skin contact. Occupational exposure is a significant concern in industries that produce or use vinyl chloride and PVC. Due to its carcinogenic properties, strict regulations are in place regarding its handling, storage, and emission levels. Environmental contamination can occur through industrial discharge and accidental spills.

Other compounds with the formula C2H3ClO include chloroacetaldehyde and chloroethanol, though these are less common in industrial applications compared to vinyl chloride. Chloroacetaldehyde is a reactive aldehyde and a possible intermediate in chemical synthesis. Chloroethanol, also known as ethylene chlorohydrin, is a toxic alcohol that has seen some use as a solvent and in organic synthesis.
