WebA small amount of ethylene is oxidized to carbon oxides and some chlorinated hydrocarbon by-products are formed. About l-2< 7o of the ethylene feed to the reactor leaves unreacted in the vent gas from the system. A simplified process flow diagram depicting an air-based fluidized bed oxychlorination system is shown in Figure 14 [22]. WebAug 1, 2024 · Fig. 9 shows the reaction pathways of ethene oxychlorination via both mechanisms, while in the ethylene oxide mechanism, 1,2-DCEA is formed via a C 2 H 4 O * surface intermediate. From the work of Higham et al. [8] , it is known that in the Deacon mechanism, the chlorination pathway begins with the formation of a ClCH 2 CH 2 * … medical terminology for difficulty speaking
