Separation of polysaccharides from rice husk and wheat bran using solvent system consisting of BMIMOAc and DMI.

A solvent system consisting of 1,3-dimethyl-2-imidazolidinone (DMI), and ionic liquid 1-butyl-3-methylimidazolium acetate (BMIMOAc) was used to separate polysaccharides from rice husk and wheat bran.

The effectiveness of AMIMCl as an extraction agent can be attributed to the prevalence of intra- and inter-molecular hydrogen bonding in cellulose.
