“…Compared with the extensive gas-liquid and liquid-liquid two-phase flow studies in microreactors [23,[45][46][47][48], limited research has been paid to the case of gas-liquid-liquid microflow [11,12,19,29]. A considerable fraction of the literature work in the latter case was focused on hydrodynamics therein [13,14,17,18,49,50], and few on the investigation of mass transfer property [12,14] and the preliminary exploration of the potential applications [21,29,30,38].
