Ozonolysis of Lignin: From Extensive Degradation to Selective Ring-Opening Oxidation. [PDF]
ChemSusChemDespite its potential as a renewable feedstock, lignin, a major component of plant cell walls and a by‐product of the pulp and paper industry, has long been underutilized. Historically, pulp mills employed ozonolysis, a powerful oxidative process, to delignify cellulosic fibers and break down lignin.
