Photocatalytic Oxidation and Alkylation Processes in Microreactors

Abstract

A microflow reaction system with immobilized a photocatalytic TiO2 layer was developed and the processes of oxidation of aromatic compounds and amine N-alkylation in microspace were examined. The photocatalytic microreactor has a remarkably large surface-to-volume ratio in comparison to conventional batch reactors and these model reactions proceeded very rapidly with considerably large efficiencies. The results suggest the feasibility of a photocatalytic microreaction system on organic reactions.
