Reactor selectivity
WebAug 21, 2024 · The strategy that we present improves reaction selectivity (by 325%) and production rates (by 30%) for the largest organic electrochemical process in industry, the electrosynthesis of adiponitrile (ADN). These advances are achieved by carefully tuning the electrochemical environment around the electrocatalyst surface and implementing data ... WebNotably, high reaction selectivity can also be established by tuning the potential difference between the electrodes. As an example, our group has shown that the oxidation of thioethers can be selectively steered to either sulfoxides or sulfones in a commercially available electrochemical flow reactor ( Figure 8 B).

Follow us to learn … The three properties are found to be: The property holds. In this reaction, 90% of substance A is converted (consumed), but only 80% of the 90% is converted to the desired substance B and 20% to undesired by-products C. So, conversion of A is 90%, selectivity for B 80% and yield of substance B 72%. See more Conversion and its related terms yield and selectivity are important terms in chemical reaction engineering. They are described as ratios of how much of a reactant has reacted (X — conversion, normally between zero and … See more Yield in general refers to the amount of a specific product (p in 1..m) formed per mole of reactant consumed (Definition 1 ).
