“…There are two main routes by which VCM is produced industrially. One is direct hydrochlorination of acetylene; , another is cracking of ethylene dichloride (EDC) provided by direct chlorination and/or oxychlorination of ethylene. The combination of direct chlorination, ethylene oxychlorination, and EDC cracking is named as the “balanced VCM process” (Figure ). In addition to the above two routes, ethane oxychlorination is another promising route for VCM production due to the economic advantage of feedstock. , However, despite the efforts of several decades, ethane-based technology is still under exploration and has not been commercialized yet.…”

“…Причому кисень в цьому процесі є не каталізатором основного процесу, а інгібітором побічних реакцій. В інших роботах [15] пропонують використовувати як каталізатор диметилформамід, стабілізований гексаметилентетрааміном. У роботі [2] реакцію хлору з етиленом проводять в середовищі рідкого ДХЕ за 0,1-1,5 МПа і 20-100 о С, але нижче від температури кипіння ДХЕ.…”

“…The annual production of 1,2-dichloroethane is approximately 54,000 ton/yr. , In this industrial process, a bubble column reactor equipped with an external recirculation loop is used at low temperatures (20–70 °C) and iron­(III) chloride is used as a catalyst to increase 1,2-dichloroethane selectivity. The reaction can be conducted in the solution as well as the gas phase. Ionic mechanism has been proposed for the liquid-phase reaction . Under these conditions, the Cl–Cl bond is polarized by the p electrons of C 2 H 4 , resulting in the heterolytic dissociation of Cl 2 .…”
