Dissolution and regeneration of wood saccharides in ionic liquids

• Cellulose is one of the most important sources of renewable biomaterials, but the number of solvents that are capable of dissolving cellulose is still today very limited. Among non-derivatizing solvents, there are even fewer alternatives. Imidazolium based ionic liquids make up a well studied group of solvents for cellulose that have many advantages such as being considered environmentally friendly, and relatively easy to recycle. Here a model substance of native cellulose, namely oligomeric cellulose with DP = 4.33 is used to study the interactions between cellulose and ionic liquid in solution using 1H NMR spectroscopy. It can be concluded that the oligocellulose is a suitable model substance, with a higher resemblance to polymeric cellulose than for example cellobiose that have previously been used but with maintained possibilities to give high resolution in 1H NMR spectres.
