Confluence microreactor

In this recently developed device shown in Fig. 5.25 [30], two immiscible liquid streams converge in a micro-channel and then separate. A well-defined flow has been demonstrated, with no entrainment of the opposed flows, for flowrates from 10 4 to 1.0 cm3 s 1. The highest flow rate corresponds to solution contact times around 1 ms, corresponding to a kL of the order of 0.1 cm s 1. Thus, the confluence microreactor has the potential to measure liquid-liquid interfacial rate constants much higher than those accessible by current methods, and interesting applications are anticipated. The device itself has been patented [31].
