Interaction of Microcrystailine Cellulose withBmimCl and AmimCl Ionic Liquids

摘要：

Microcrystalline cellulose (MCC) was treated with two kinds of ionic liquids(ILs), 1-n-butyl-3-methylimidazolium chloride(BmimCl) and l-n-allyl-3-methylimidazolium Chloride (AmimCl), in order to disrupt MCCs highly crystalline structure and then enhance MCCs hydrolysis rate. Primarily, MCCs structural changes were discussed in detail by FTIR, CP/MAS 13C NMR, XRD and XPS. MCC was found to have undergone characteristic structural changes during interaction with ILs. The acid hydrolysis rates were around 2 times higher for modified MCC treated by ILs as compared to untreated MCC. Treatment of BmimCl could increase hydrolysis rate higher than treatment of AmimCl.
