Preparation and Properities of Microcrystalline Cellulose from Corn Stalk
Corn stalk was used to prepare microcrystalline cellulose (MCC) and product properties were studied.The optimal parameters for MCC preparation were founded to be 8％ (w/w) of H2SO4,hydrolyzing time 90 min and temperature 85 ℃,which resulted in a polymerization degree of 292,a content of 92.6％,a yield of 76.48％ and a crystallinity of 74.5％ for cellulose.Under these conditions,MCC retained the original morphological structure with high crystallinity and thermal stability,thus possessing favorable properties for future use.
