Presentation title : Plasma flow reactor for functionalization of small organic molecule

Abstract : Plasma is a powerful technology for the generation of reactive species without any catalyst. It is currently used for the modification of materials in several areas of industry but underused in the field of small molecules due to the lack of accessible plasma reactor in liquid phase. The “Plasma, Processes, Microsystems” team (2PM), headed by Prof. M. Tatoulian, has developed therefore since 2013 gas-liquid two-phase flows micro-structured reactors coupled to plasma devices able to generate in a controlled way gaseous reactive radical species in close contact to a flowing liquid phase. Preliminary results demonstrated the proof of concept with various types of cyclohexane and benzene functionalizations using different gases (O2, H2, NH3, CO). Since then, this unique association of plasma and microfluidics is studied to explore new functionnalizations, such as acylation or methylation, starting from various types of substrates. The presentation aims to show that plasma technology could open up new opportunities to functionalize organic molecules in a simple and effective way in metal-free conditions (no catalyst) at ambient temperature and pressure.
