FAQ

What are the physical and chemical properties of Chloroethene (CAS: 63231-66-3)?

Chloroethene (1,2-dichloroethane) has a molecular weight of approximately 98.96 g/mol and a density of 1.205 g/cm³. It is slightly soluble in water but miscible with most organic solvents. It is mildly reactive, particularly with water and basic solutions, leading to the formation of chloroacetic acid. Chloroethene is a colorless, flammable liquid with a slight chloroform-like odor.

How is Chloroethene (CAS: 63231-66-3) typically synthesized?

Chloroethene is typically synthesized through the chlorination of ethene. This process involves the addition of chlorine to ethene in the presence of a Lewis acid catalyst, such as ferric chloride. The reaction is exothermic and selective, yielding high yields of 1,2-dichloroethane. The reaction conditions are carefully controlled to ensure the desired product is formed with high selectivity.

What industries use Chloroethene (CAS: 63231-66-3)?

Chloroethene (1,2-dichloroethane) is widely used in the polymer industry for the production of polyvinyl chloride (PVC). It is also used in the production of chlorinated solvents and as a starting material for the synthesis of other chlorinated organic compounds. Additionally, it has applications in the pharmaceutical industry for the production of intermediates and in the manufacturing of sensors and semiconductors.

What precautions should be taken when handling Chloroethene (CAS: 63231-66-3)?

When handling chloroethene (1,2-dichloroethane), it is essential to wear personal protective equipment (PPE) such as gloves, goggles, and a laboratory coat. Work should be conducted in a well-ventilated area or a fume hood to prevent inhalation. Spills should be cleaned up immediately using appropriate absorbent materials. In case of exposure, seek medical attention. Always consult the Safety Data Sheet (SDS) for detailed emergency procedures and safe handling guidelines.
