- Abstract
- The saw dust of tropical hardwood, Nyatoh(Palaquium Spp.), was used as a raw material for the preparation of the high valued microcrystalline cellulose(MCC). Three pulping methods, soda pulping, Kraft pulping, and acid-sulfite pulping were applied to obtain cellulose from the saw dust. The residual impurities were removed with the additional bleaching processes: (A) ClO_2→H_2O_2; (B) ClO_2→O_3; (C) O_3. For the acid treatment for MCC preparation, the H_2SO_4, with three concentration, 20%, 40%, 60% were applied and the effects of H_2SO_4 concentration on the properties of MCC were evaluated. The results indicated that the MCC obtained by acid-sulfite pulping followed with O_3 treatment and 40% H_2SO_4 treatment showed less residual lignin, higher brightness and crystallinity than that of Avicel MCC.
