Reactor selectivity
WebT1 - Reactor selectivity based on first‐order closures of the turbulent concentration equations. AU - Brodkey, R. S. AU - Lewalle, Jacques. PY - 1985/1. Y1 - 1985/1. N2 - Toor's (1969) hypothesis is extended to the second‐order, series‐parallel reaction. A second closure relates the mixing for the second reaction to the first. WebMar 9, 2024 · Selectivity is typically achieved through chemical approaches. Recently in Nature, Yu, Lin, and co-workers disclosed an electrochemical carboxylation of N -heteroarenes with site selectivity tunable through reactor configurations. Using divided and undivided cells, they achieved C5- and C4-carboxylations, respectively, of 2-arylpyridines.
