ABSTRACT

Cellulose is basically a simple linear chain that is the basic component of all plants and it is a natural homopolymer. Microcrystalline cellulose is actually partially pure depolymerized cellulose and it is obtained from the hydrolysis by mineral acids of lignin-free soft plant fiber. Although the main source of raw material for microcrystalline cellulose production is virgin soft or hardwood, jute sticks are quite useful as an alternative source of raw material. The percentages of jute stick moisture, cellulose, hemicelluloses, lignin and ash have been determined by standard methods and these results are cellulose 38-42(%), lignin 22-26(%), pentosan 22(%) and fiber Length 0.8-1.0mm, respectively. The cellulose purity of BJRI Tossa jute stick is identified by FT-IR spectroscopy. The IR results of the MCC analysis indicated 3450.85cm-1 for the OH stretching vibration of all jute sticks' cellulose, 2911.41cm-1 is attributed to the C-H stretching vibration of polysaccharides, and 1655.45cm-1 for the bending mode of the absorbed water molecules. In thermogravimetry analysis, in the first phase, 50–110oC is associated with moisture decomposition. The organic matter decomposition of jute stick MCC occurred in the range of 100-260oC. At 450oC, the remaining 1.22-1.37% of inorganic material ash was obtained. In this study, we have tried to find out the easiest way the release alpha-cellulose and MCC from jute sticks, which can be nicely applicable in various fields such as coatings, food, pharmaceuticals, adhesives, cosmetics, membranes, films, explosives, tobacco, and the textiles industry.
