Abstract
This work presents a detailed analysis of various industrial syntheses of vinyl chloride according to material and energy efficiency green metrics. The routes examined are hydrochlorination of acetylene, oxyhydrochlorination of ethane, and tandem hydrochlorination of ethylene and dehydrochlorination of 1,2-dichloroethane. The green metrics selected are process mass intensity (PMI) and input enthalpy per unit mass of product measured in MJ per ton.
