Hydrolysis Of

Cellulose is one of the largest components in corncobs. Cellulose was obtained from corncob in this research that has a yield of 19.6% of 20 grams of corncob powder. The isolated cellulose was characterized by using FTIR and SEM. Cellulose has crystalline chain and insoluble in water or organic solvents. The molecular chain of cellulose is linear and has intra- and inter-molecular hydrogen bonds. One way for cellulose to be easy in the treatment of applications, is to convert microcrystalline cellulose into nanocrystalline cellulose. Nanocrystalline cellulose can be obtained by several methods, one of them by acid hydrolysis. Hydrolysis of cellulose by using sulfuric acid produces nanocrystalline cellulose. Nanocrystalline cellulose can be characterized by using TEM and PSA analysis. CNC 60 has a particle size distribution with a diameter range of 14.3 nm - 45.0 nm and an average diameter of 17.4 nm. Whereas cellulose with CNC 90 has a smaller particle size distribution with a diameter range of 10.0 nm - 17.1 nm and an average diameter of 11.9 nm.

Acid Process

The formation of metatitanic acid particles in the form of rutile TiO2 is an important step in the sulfuric acid process used to manufacture white pigment. F value, temperature and stirring speed were investigated to study their influence on the particle size and distribution in this paper. The results showed that suitable size and narrow particle size distribution were obtained in metatitanic acid on the condition that F value was 2.02, the temperature was 95°C and the stirring speed was 300r/min. Metatitanic acid was calcined above 850°C to form rutile TiO2. The crystal structure and micromorphology of TiO2 were characterized by XRD and SEM, respectively. The results demonstrated that a rutile TiO2 with high crystallinity was prepared.
