Abstract:
A method of obtaining an aqueous solution of an alkali acetate from lignocellulose, wherein lignocellulose is treated with a first aqueous extraction solution having a pH value in the range of 12 to 14 and a content of a C1-4 alcohol, in particular ethanol or isopropanol, in the range of 40% to 90%, in particular of from 75% to 85%, whereby a first aqueous solution of an alkali acetate is obtained, and wherein said first solution of an alkali acetate is used to treat additional lignocellulose in order to enrich additional acetate in said first solution.
