Preparation and characterization of reed MCC in ionic liquids
摘要
Abstract
The feasibility and technology of preparing microcrystalline cellulose (MCC) in ionic liquid system were studied ,and its property was compared with commercial MCC.The cellulose in ionic liquid system were optimized through the method of conditional test using reed pulp as raw material and [BMIM ]Cl as solvent. The chemical composition and structure of MCC samples were characterized by FT-IR , XRD and TGA. The results showed that the prepared MCC with polymerization degree (DP) of 438.86 ,crystallinity of 77.97% ,yield of 84.80% ,dissolvability of 0.38% and ash of 0.05% under the reaction temperature of 75 ℃ ,reaction time of 3 h and cellulose concentration of 2.5%.The results of FT-IR and XRD showed that the crystallization structure of prepared MCC was in type of cellulose Ⅰ ,and had better thermal stability than commercial MCC.关键词
