Continuous falling film microreactor

In 2010, the authors described the ozonolysis of 1-decene (61) in different solvents (dichloromethane, methanol, and a mixture of both) [35]. Results obtained in the falling film microreactor were compared to those obtained in a semibatch reactor with continuous ozone dosing to the reaction mixture. The reaction mechanism and the assumed species in the reaction mixture are summarized in Figure 6.33. 

Two classes of gas-liquid microchannel reactors were developed in the past years -continuous-phase contacting falling film, overlapping charmel, mesh, and annular flow approaches, and dispersed-phase contacting by Taylor flow reactors, micromixers for bubble and foam formation, and miniaturized packed bed microreactors, which follow classical trickle-bed operation at smaller scale. Recently integration of operations inside a microdevice has been studied and led to the development of membrane microreactors.
