To compare the values obtained using the pRS-SDR to those of other reactors which carried out the photooxygenation of α-terpinene, we compared the reported productivity (Table ). As can be seen, the pRS-SDR far outperforms other reactors reported in literature and it does not rely on specialized operating conditions as the nebulizer reactor , where aerosols are generated for high productivity; or the thin film rotary reactor, which operates in a semi-batch fashion .
