Abstract: A method of processing a lignocellulosic feedstock includes heating the lignocellulosic feedstock in a solvent mixture comprising an acid and at least 80% by volume of n-butanol to produce a reaction mixture including a butylated lignin. A butylated lignin product wherein at least 85% of the β-Ο-4 linkages include n-butyl ether groups can be prepared. Cellulose and butylated hemicellulose products can also be obtained.

Abstract: A method of depolymerising a lignin includes oxidising the lignin to provide an oxidised lignin wherein benzylic –OH of β-O-4 linkages have been converted to carbonyl. The oxidised lignin is depolymerised with a metal selected from the group consisting of zinc, magnesium, aluminium and titanium or mixtures thereof, in the presence of an ammonium salt or carbon dioxide. Also described are methods for manufacturing phenolic products from lignin and a method for the cleavage of a β-O-4 linkage in a substrate.
