Chemical Degradation Methods: Permanganate Oxidation
Much of our current knowledge about the structure of lignin in wood and pulp is based on results obtained from permanganate oxidation. This method involves the selective degradation of all aliphatic side chains attached to aromatic moities in lignin, resulting in the formation of a mixture of aromatic carboxylic acid structures henceforth referred to as “acids”. The identity of these as well as the amount of each individual acid provides information about the substitution pattern in a particular lignin and the frequency with which individual linkages between phenylpropane units occur.
