Nishide and Heard reports a novel recyclable acid catalysts for use in esterification, Friedel-Crafts acylation and other condensation reactions. The team from Waseda University in Japan and Monash University in Australia reports the synthesis of high-density poly(vinylsolfonic acid)-grafted solid acid materials with extremely high acid dissociation abilities.
They found the catalyst to possess interesting anti-corrosive properties implying that reactor corrosion is minimised. The process introduces “a new avenue to carry out such solid-phase acid catalysed synthetic reactions in a more benign, green chemical manner, whilst minimizing pollution/contamination risks due to leading to minimum risks of reactant contamination due to corrosion”, claims Hearn and co-workers.
