Process intensification: oxidation of benzyl alcohol using a continuous isothermal reactor under microwave irradiation
R. J. J. Jachuck, D. K. Selvaraj and R. S. Varma
In the past two decades, several investigations have been carried out using microwave radiation for performing chemical transformations. These transformations have been largely performed in conventional batch reactors with limited mixing and heat transfer capabilities. The reactions were performed under adiabatic conditions where the enhancements in the reaction rate reported in these publications may be due to the rapid increase in the reaction temperature during the course of the reaction. The concept of process intensification has been used to develop a narrow channel reactor that is capable of carrying out reactions under isothermal conditions while being exposed to microwave irradiation. Oxidation of benzyl alcohol to benzaldehyde has been carried out using the above-mentioned isothermal micro reactor. Results and the findings of this investigation are discussed in this paper.
