Abstract

Sustainable Chemical Synthesis of High Added-Value Compounds from Renewable Sources in Flow Regime

Julio Cezar Pastre, Associate Professor, University of Campinas – UNICAMP

Raw materials from renewable sources, as well as agro-industrial waste, represent an attractive source of useful chemical functionalities. Our research group has already identified continuous flow processing as a fundamental technology for the valorization of such materials. Flow chemistry offers unique opportunities for the conversion of biomass derivatives into chemical compounds with higher-added value, since it brings numerous advantages in terms of unique process experience, scalability, and reduced environmental footprint. In this context, we will present our efforts for the synthesis of platform molecules (such as furanics) and new chemicals (monomers, nitrogenated aromatics) from biomass derivatives.
