Abstract:

A research has been done on the production of cellulose acetate films from oil palm logs (Elaeis guinensis Jack) with chloroform as solvent and triacetin as plasticizer. Cellulose from oil palm sawdust obtained by alkalization process with addition of 2% NaOH. The bleaching process was carried out with addition 2% of NaOCl, 8 drops of glacial CH3COOH and heated at 60-70°C while stirring for 1 hour. The obtained residue was added with 0.05 N HNO3 and heated at 70°C for 1 hour. The obtained cellulose is synthesized to cellulose acetate by the addition of glacial acetic acid as an activator to allow the esterification reaction to proceed smoothly. The acetylation process was carried out by addition of catalyst acetic anhydride acid and H2SO4. The obtained cellulose acetate was formed into a cellulose acetate film with a chloroform solvent and a variation amount of plasticizer triacetin 0 mL, 0.5 mL, 1 mL, and 1.5 mL. Functional group analysis was determined by FT-IR and showed the presence groups of -OH, C-H, C-O for cellulose and groups of -OH, C-H, C-O, C=O for cellulose acetate and cellulose acetate film. The mechanical analysis was determined by tensile test and showed cellulose acetate added with triacetin (1.8:1.5 (w / v)) having an optimum yield of 156,701 MPa, strain 0.0269 and Young's Modulus 3725.4 MPa. Thermal degradation analysis with TGA ie good heat stability occurred at temperature 294,25oC and residual mass 1,9%. Morphological analysis with SEM is at 1000 times enlargement, the distribution of pore film spread evenly, has a smooth surface, pores are small and homogeneous.
