Chemoselective aerobic oxidation of aliphatic alcohols in lignin in micellar system

Abstract

A micellar catalytic system for chemoselective aerobic oxidation of primary alcohol in the diol fragment guaiacylglycerol-guaiacyl ether as one of the most common structure in lignin has been proposed. The catalyst system consists of TEMPO/Cu (II), mediated by oxygen gas. Our studies highlight the prospect of combining this method with a PEO-PPO-PEO micellar system in basic aqueous effluent of delignification processes of lignocellulosic materials to achieve the oxidation of primary alcohol to aldehyde.
