Abstract:
Pineapple leaf fiber (PALF) is an agricultural residue that is available abundantly as a renewable resource with high cellulose content. Sulfuric acid (SA) treatment is commonly used for producing cellulosic products. This work investigated the effect of temperature on cellulosic products from PALF via SA treatment. SA at low temperature (-20 degrees) broke down the H-bonding that led to the production of regenerated amorphous cellulose (RAC). On the other hand, SA at high temperature (50 degrees) hydrolyzed cellulose by breaking β-1,4-glycosidic linkage that led to nanocrystalline cellulose (NCC). FTIR spectra showed changes in chemical bonding of RAC comparing to that NCC: O-H stretching corresponding to inter-molecular H-bonding between O(6)H⋯O'(3) (3285 cm-1) and intra-molecular H-bonding of O(3)H⋯O(5) (3331 cm-1) disappeared, transformed to weak H-bonding (3490 cm-1); CH2 scissoring of C(6) or crystalline absorption band (1427 cm-1) decreased while C-O-C valence vibration representing amorphous region (897 cm-1) increased. Cellulosic products also showed different optical phenomena under cross-polarized light, attributing to their crystalline or amorphous structures. This work not only provided an understanding of the effect on temperature on SA treatment of PALF but also suggested economical means for obtaining cellulosic products of various forms.
