Abstract: A method for processing lignin may comprise flowing a lignin composition comprising a lignin polymer and a solvent through a reaction chamber of a continuous flow reactor, the lignin polymer comprising hydroxycinnamic groups bound to a polymeric backbone; flowing ozone through the reaction chamber containing the lignin composition under conditions to maximize oxidative cleavage of the hydroxycinnamic groups to produce one or more types of aromatic monomers while minimizing oxidative cleavage of the polymeric backbone; and collecting the one or more types of aromatic monomers, e.g., by a size-selective membrane separation device.

Abstract: A process for the ozonolysis of an alkane may comprise combining an alkane and ozone in a liquid phase medium comprising CO2 under conditions sufficient to oxidize the alkane to produce one or more non-combustion products. The liquid phase medium may be free of a super acid.
