Influence of acid hydrolysis reaction time on the isolation of cellulose nanowhiskers from oil palm empty fruit bunch microcrystalline cellulose
Cellulose nanowhiskers (CNW) were successfully isolated from oil palm empty fruit bunch microcrystalline cellulose (OPEFB-MCC) through sulfuric acid (H2SO4) hydrolysis with different reaction times. OPEFB-MCC was hydrolyzed with 64 wt.% H2SO4 at 40 °C and various reaction times (30, 60, and 90 min)....
