Application Note 43 – Singlet oxygen reaction in continuous flow, an example of an ene reaction.
This application note demonstrates the use of singlet oxygen in flow. A range of parameters are investigated that determine the conversion and throughput. The ene like reaction of singlet oxygen with citronellol is used as a model. The versatility of the V-3 pump is showcased by the simultaneously pumping of both the reagent solution and gaseous oxygen. The bi-phasic gas / liquid mixture enters the reactor in Taylor flow. On exiting the UV-150 photochemical reactor the bi-phasic flow is no longer seen as the majority of the gas is consumed in the reactor. Further, by using a variable backpressure regulator, reaction parameters are controlled individually and optimized. Significant advantage is shown over traditional batch singlet oxygen reactions in which some reaction parameters are difficult to control.Join the Vapourtec Knowledge Base to access this Application note
