Abstract (en)
[origin: WO2014094104A1] The present disclosure related to Organosolv processes for recovery of lignin derivatives from lignocellulosid feedstocks chosen from i) hardwood, ii) softwood, and iii) annual fibre. The lignin derivatives from each of these feedstocks have a certain aliphatic hydroxyl content. Specifically, i) 2.35 mmol/g or less from hardwood; ii) 7.0 mmol/g or less from softwood, and iii) 1.00 to 3.75 mmol/g from annual fibre. Stable and predictable antioxidant activity is provided by selecting for derivatives of native lignin having these specific ranges of aliphatic hydroxyl contents.
