Analysis of Hydrogen Bonding Network in the Systems Containing Chloride-Based Ionic Liquids with Cellulose/Cellobiose by Fourier-Transform Infrared Spectroscopy

Hydrogen bonds formed upon dissolution of cellulose and cellobiose in ionic liquids, 1-butyl-3- methylpyridinium and 1-butyl-3-methylimidazolium chlorides, have been analyzed and characterized by means of Fourier-transform infrared spectroscopy and quantum-chemical calculation. The obtained data have been used for assignment of absorption bands of individual OH groups and determination of hydrogen bonds energy in the solutions.
