Study of the Direct CO2 Carboxylation Reaction on Supported Metal Nanoparticles

2,5-furandicarboxylic acid (2,5-FDCA) is a biomass derivate of high importance that used as building block in the synthesis green polymers such poly(ethylene furandicarboxylate) (PEF). PEF presumed to be an ideal substitute for predominant polymer industry, terephthalate) (PET). Current routes 2,5-FDCA require 5-hydroxymethylfurfural (HMF) reactant, which generates undesirable co-products due complicated oxidation step. Therefore, direct CO2 carboxylation furoic salts (FA, produced from furfural, inedible lignocellulosic biomass) potentially good alternative. Herein, we present primary results obtained on reaction potassium 2-furoate (K2F) synthesize 2,5-FDCA, using heterogeneous catalysts. An experimental setup was firstly validated, and then several operation conditions were optimized, catalysts instead semi-heterogeneous counterparts (molten salts). Ag/SiO2 catalyst showed interesting regarding K2F conversion space–time yield 2,5-FDCA.
