Title: Characterization of Products from Base Catalyzed Depolymerization of Lignins to Determine Changes in Chemical Structure

Benzle ether linked dimers can be cleaved with 0.05% NaOH. Diphenyl ether dimers are more resistant. Some biphenyl products observed. Extent of depolymerization appears to be limited by some condensation reactions involving C-C bond formation.
