Characterization of lignin streams during ionic liquid/hydrochloric acid/formaldehyde pretreatment of corn stalk

•FA stabilized lignin was obtained from [C4C1im]Cl/HCl/FA pretreatment of biomass.•FA stabilization influenced structure feature of lignin fractions.•Lignin with high molecular weight and low S/G ratio was recovered.•FA stabilization changed the compositions of degraded products from lignin. This wo...
