Daftar Isi:
- A study about the influence of time on the hydrolisis of "rice straw " to produce microcrystalline cellulose has been done. The hydrolytic process was conducted in 2,5 N hidrochloric acid solution at 100oC for 1 hour, 1,5 hours, 2 hours, 2,5 hours respectively. The physical properties of microcrystalline cellulose yielded were compared to those of Vivacel®102. The results indicated that there was a decrease in the true density value with the increase in hydrolytic time of the microcrystaline cellulose yielded, where as its water adsorption capacity, tapped ani untappeo density values increased. Noticing the physical properties of microcrystalline cellulose, it seemed that the physical properties of microcrystaltine obtained from hydrolisis of the "rice straw " in 2,5 N hydrochloric acid solution at 100o C for 1,5 hours the were more similar to those of Vivacel® 102.
