Beneficial Micro Reactor Properties for Photooxidation of Dienes

2 Beneficial Micro Reactor Properties for Photooxidation of Dienes 

Concerning safety issues, micro reactors are beneficial as they efficiently remove the reaction heat and also may intrinsically prevent explosions by terminating the radical chains. This has been impressively shown for the reaction between hydrogen and oxygen, widely known as being very dangerous [75, 76]. 

Owing to the small length scales in micro reactors, e.g. 50 pm, high concentrations of a sensitizer may be used [21]. As these materials typically have high costs. 

Low-intensity light sources should give efficient irradiation of thin liquid layers [21]. Sample heating is reduced and so is radical recombination. In addition, oxygen enrichment of solutions before and after micro reactor passage can be handled differently and is no longer a major safety problem [21].
