  • Selective C—O bond cleavage of oxidized lignin and lignin-type materials into simple aromatic compounds
    Patent number: 9359391
    Abstract: A method to cleave C—C and C—O bonds in ?-O-4 linkages in lignin or lignin sub-units is described. The method includes oxidizing at least a portion of secondary benzylic alcohol groups in ?-O-4 linkages in the lignin or lignin sub-unit to corresponding ketones and then leaving C—O or C—C bonds in the oxidized lignin or lignin sub-unit by reacting it with an organic carboxylic acid, a salt of an organic carboxylic acids, and/or an ester of an organic carboxylic acids. The method may utilize a metal or metal-containing reagent or proceed without the metal or metal-containing reagent.
