Abstract

Extracted cellulose from oil palm empty fruit bunch fiber (OPEFB) was subjected to acid hydrolysis in producing microcrystalline cellulose (MCC). The acid hydrolysis was conducted using 1 % (v/v) sulfuric acid (H2SO4) at varying temperatures of 120, 130 and 140 °C for an hour. The relationship between the thermal behavior and physical properties was investigated by thermogravimety (TGA/DTG) and differential scanning calorimetry (DSC) as well as x-ray diffractometry (XRD). The hydrolyzed MCC at 120 °C (MCCA) showed the highest thermal stability temperature and percentage of crystallinity at 250 °C and 65.07% respectively. However, hydrolyzed MCC at 130 °C (MCCB) and 140 °C (MCCC) exhibited low thermal stability temperature at 225 °C and 220 °C respectively. The percentage of crystallinity obtained for MCCB and MCCC was 61.18% and 60.64% respectively. This study revealed that the degree of crystallinity for cellulose has positive impact on the thermal degradation temperature of the OPEFB-MCC.
