When working with an emulsion (and particularly with a heterogeneous catalyst) the mass transfer between the phases is critical. Insufficient mixing leads to lower interfacial area per volume, and in turn to poor mass transfer across the phases.
Emulsions are prominent in chemical processing and the manufacturing of many products. Some examples are:
SpinChem’s rotating bed reactor (RBR) has been proven for many applications involving emulsions. Among others:
This video shows the ability of the rotating bed reactor (RBR) to form an emulsion of two immiscible solvents: water and dichloromethane (50/50 by volume). The dye, initially dissolved in the organic phase, is transformed (de-protonated) by an ion exchange resin in the RBR, and extracted into the aqueous phase.
