Chlorination of ethylene
WebApr 6, 2024 · Nearly all production of VCM is based on ethylene, which is first reacted with chlorine to make ethylene dichloride (EDC). There are two routes commonly used to make EDC: direct chlorination using pure chlorine and ethylene, and oxychlorination in which the ethylene reacts with chlorine in hydrogen chloride.
