Structural changes in lignocellulosic biomass during activation with ionic liquids comprising 3-methylimidazolium cations and carboxylate anions

Table 1 Mass recovery of hybrid poplar biomass (HP %) after activation with two ionic liquid types under varying times

Activation time (h)	Biomass mass recovery^a (% mean ± SD)
Activation time (h)	[EMIM][CH₃COO]	[AMIM][HCOO]
3	96.1 ± 0.2	98.2 ± 0.0
24	96.1 ± 0.2	96.8 ± 0.4
48	96.1 ± 0.5	93.2 ± 1.0
72	94.1 ± 1.0	92.1 ± 0.8

^aSD or standard deviations for mass recovery were calculated based on triplicates
