Degradation of cellulose catalyzed by imidazolium perrhenate
摘要
Abstract
Imidazolium perrhenate was applied as the catalyst to promote the degradation of microcrystalline cellulose ( MCC) with the solvent of ionic liquid 1-allyl-3-methyl imidazolium chloride ( [ Amim ] Cl ) . The effects of reaction temperature, reaction time, reactant concentration, the amount and structure of catalyst on the degradation of cellulose were studied in details. When using 5% of [ mim-( CH2 ) 3 SO3 H ] ReO4 , 70 μL of water, 0. 1 g cellulose and 2. 0 g [Amim]Cl under microwave irradiation for 30 min at 160℃, 89. 6% of total reducing sugar ( TRS) and 46. 7% of glucose yield can be obtained. The degradation mechanism of cellulose catalyzed by imidazolium perrhenate was also studied. The hydrogen bonding between hydroxyl groups of cellulose and ReO4 anion and aromatic ring cation of catalyst is assumed to be the key step for depolymerization of cellulose.关键词
