In this study, the objective of this work was to delevop a simple extraction and characterization of regenerated cellulose from oil palm wood. The purpose of this research is to extract cellulose from oil palm wood according to TAPPI test method. The extracted cellulose was treated with ionic liquid, BMIMCL at different weight percentange (2 wt % and 5 wt %). The chemical, structural, morphology and thermal properties of cellulose samples (untreated and treated cellulose) were characterized using X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Field Emisssion Scanning Electron Microscope (FESEM) and Thermogravimetric Analysis (TGA) respectively. In this study, the cellulose treated cellulose with BMIMCL is find out more amorphous properties compared to untreated cellulose. This proves that BMIMCL ionic liquid is effectively in convert the cellulose into amorphous cellulose. However, the BMIMCL is less efficient in conversion from cellulose to nanocellulose.
