The ionic solvent, 1-butyl-3-methyl imidazolium chloride was used to dissolve the samples. Two lignocellulosic material including bagasse soda lignin and Populus deltoides wood flour were used. One gram of samples were dissolved in 10 ml ionic solvent, 1-butyl-3-methyl- imidazolium chloride at 70 ºC for 72 h while stirring with a magnetic stirrer. The wood flour and lignin samples were acetylated with addition of acetic anhydride to each container with a ratio of 0.25 ml/ 0.25 ml. The samples were heated for 3 days at 110 ° C. Two control samples (without acetylation) and two treatments (acetylation) were used. The functional groups were determined using FT-IR Spectrometer. The number and type of carbon and their structure were examined using ¹³CNMR Spectrometer. The guaiacyl, syringyl, coniferyl alcohol and biphenyls structures were identified.
