Latest Patents

Rafiee's latest patents include innovative methods for selectively modifying lignin. His work involves electrochemically oxidizing lignin using stable nitroxyl radicals. This process selectively oxidizes primary hydroxyls on β-O-4 phenylpropanoid units to corresponding carboxylic acids while leaving the secondary hydroxyls unchanged. The result is polycarboxylated lignin in the form of a polymeric β-hydroxy acid. This polymeric compound has a high loading of carboxylic acid and can be isolated in acid form, deprotonated, or converted to a salt. Furthermore, the β-hydroxy acid, anion, or salt can undergo acidolysis to generate various aromatic monomers or oligomers. The initial oxidation of lignin enhances its susceptibility to acidolysis, thereby improving the yield of aromatic monomers and oligomers.
