Eucalyptus globulus was used as feedstock and was provided by CIFOR-INIA (“Centro de Investigación Forestal-Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria”, in Spain). The ionic liquid 1-methylimidazolium chloride ([Mim][Cl], 98% purity) was supplied by Iolitec GmbH. Ethanol was used as antisolvent and supplied by Panreac (96% purity). N,N-Dimethylformamide (DMF, ≥99.9%, Panreac) and ReadyCal Kit PMMA standards (Polymer Standards Service GmbH) were used in GPC analysis.
1 methylimidazolium chloride
1-methylimidazolium chloride is a chemical compound with the formula C4H7N2+Cl-. It is a white crystalline solid that is soluble in water and other polar solvents. The compound is commonly used as a building block in the synthesis of other chemicals and materials.

Synthesis and Characterization of Ionic Liquids
1-Butyl-3-Methyl Imidazolium Bromide (BMIM Br) was prepared according to the procedure described by Wu et al. 29 . 1-Butyl-3-MethylImidazolium bis(trifluoromethyl)sulfonyl imide (BMIM TFSI) was also prepared according to Wu et al. procedure 29 , slightly modified. Briefly, 1.1 eq LiTFSI and 1 eq BMIM Br were mixed in ultra pure water during 16 h at room temperature. The solid obtained was then washed 4 times with ultra pure water and dried by evaporation under vacuum during 24 h at 80 °C.
Density and viscosity of ionic liquids were determined using respectively a DMA 4100 densimeter and a Lovis 2000 viscosimeter, both from Anton Paar®.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
