Abstract

Cellulose acetate was synthesized from cellulose which was isolated from teak wood (Tectona grandis) biowaste. The isolation process used an isolation method using nitric acid, sodium hydroxide, sodium sulfite and bleaching with calcium hypochlorite. Cellulose acetate was synthesized with acetic anhydride, toluene as a solvent, and sulphuric acid as a catalyst. Cellulose acetate reacted with acetic acid as a catalyst and glycerol-chitosan as a plasticizer. This product yielded a bioplastic. The synthesized products were characterized by using FTIR and SEM. The bioplastic’s mechanical properties were evaluated by ASTM D638 method. Based on the results of FTIR analysis, this result was successfully performed. This condition was shown by the sharpness of the hydroxyl group of cellulose acetate than the hydroxyl group in the cellulose and wood powder. The optimum result of bioplastic was obtained by composition of cellulose acetate: acetic acid: chitosan: glycerol is 0.8 g: 15 mL: 0,4 g: 1 mL. © 2018 Oriental Scientific Publishing Company.
