Understanding the Production and Stability of Aldehydes through the Catalytic Oxidation of Native Lignin to Phenolic Monomers

Maria Martinez*

Although the catalytic oxidation of lignin to produce phenolic monomers with aldehydes as the primary products is highly appealing, the yield of desired monomers is still only moderate. The purpose of this research is to examine the reaction mechanism for lignin to aldehyde conversion and aldehyde stabilization in alkaline media. Studies on the stability of pure aldehydes have shown that condensation and over oxidation to carboxylic acids are the main causes of low yield. Real lignin was depolymerized utilizing a chemical protection approach and the theoretical maximum monomer production was attained in 30 minutes at 160°C using aniline as the capping agent.
