Photoreactor homogeneous

Equation (45) can be solved by applying different photoreactor models. The literature reports several photochemical reactor models for both homogeneous and heterogeneous reactors [11,108,109]. In practice, annular photoreactors are often used (see Fig. 5) therefore, models for this type of reactor are considered here. For other types of reactors, attention should be given to other publications [109].

One advantage of microstructures for photooxygenation reactions lies in the formation of thin liquid layers, which allows higher spatial illumination homogeneity, an irradiation of the complete solution inside the reactor, and also a shorter distance between the irradiation source and the solution. In addition, microfluidic reactors exhibit a low liquid phase holdup of explosive intermediates such as peroxides that are formed during photooxygenations. Furthermore, these products can immediately be quenched after leaving the photoreactor.
