Unconventional media and activation methods for green chemistry: strategies, benefits and limitations (Inv. Conf.)

Abstract : The research work about the investigation of unconventional media and methods of activation will be presented. Different green chemistry applications have been explored in several fields such as organic chemistry, biomass valorization, catalysis, energy, separation, etc. Mechanistic studies have also allowed understanding some fundamental aspects of the studied systems. The research involving ionic liquids and power ultrasound will be particularly reported through different studies: (1) ionic liquids/sonochemistry combination; (2) ionic solvents/catalysts for the valorization of biomass; (3) sonochemistry for the preparation of bio-based functionalized molecules. Ionic liquids are solvents composed of ionic species (salts) with a low melting point, usually less than 100 °C. They generally result from the combination of a bulky organic cation and an anion, organic or not. The term “sonochemistry” is used to describe the chemical and physical processes that occur in solution through the energy provided by ultrasound. The effects of ultrasound are directly related to the phenomenon of cavitation which is the formation, the growth and the implosion of gaseous bubbles in a liquid medium. The sudden implosion of these gas bubbles of a few micrometers in diameter is accompanied by very intense local mechanical and chemical effects, at the base of all the applications of sonochemistry. The current research projects developed at the Université Savoie Mont Blanc on the use of unconventional activation methods for fine chemistry and biomass/waste valorization will be also presented.
