Degradation of a Phenolic β-O-4 Lignin Model Dimer by Electrochemically Mediated Delignification System with Violuric Acid

Abstract:

The β-O-4 type model compound guaiacylglycerol-β-guaiacyl ether was treated with a Violuric acid (VIO) mediated electrochemical delignification system. GC-MS analysis were used to investigate the changes of chemical structure of β-O-4 type model compound during reaction. Mechanism of this electrochemical delignification was also explored. Results indicated that the electrochemical oxidation by VIO as a mediator had strong oxidation capability on degradation of β-O-4 type model compound. After degradation, a series of aromatic compounds containing single benzene ring, furan compounds and aliphatic compounds with small molecule were produced. From their structures, the following reactions were caused by electrochemical oxidation: ether-bond cleavage, C_α-C_β cleavage and benzene ring cleavage. Corrsequently, this work provides a comprehensive information on electrochemical oxidation delignification system that could be applied to industrial nonpollution bleaching.
