“…40 Herein, the phase contacting is intensified using, for example, multiple stirrers, 10,41 various stirrer geometries in a stirred tank reactor, 42 static mixer reactors, 43 or ejector loop reactors. 44,45 The aqueous biphasic hydroformylation of long-chain olefins has been discussed to take place either in the catalyst bulk phase or at the liquid−liquid (LL) interface, with the latter being favored in the literature on the basis of estimations of the Hatta number, a comparison of the reaction rates of olefins with different carbon chain lengths, an observed first-order dependence on the olefin concentration in the organic phase, and a proposed linear dependence of the rate of reaction on the LL interfacial area. 39,42,44,46 Recently, our group showed that, in a mixture of α-olefins of varying carbon chain lengths, the individual rates of conversion do not correlate with the individual water solubilities but with their respective mole fraction in the organic phase.…”
