Cellulose, chitosan and chitin are the most abundant biodegradable natural polymers. These polymers have found a wide spectrum of applications in different industries. The dissolution of these polymers in conventional solvents is restricted by many inter- and intra-molecular hydrogen bonds repeated in a specific pattern. These periodically repeated hydrogen bonds are held responsible for formation of a rigid network and hence, limited applications of the mentioned polymers. Overall, since many applications of the above-mentioned polymers depend on the dissolution process, synthesis a useful solvent to dissolve cellulose is of great importance and still controversial. Ionic liquids (ILs) can be considered as powerful solvents for dissolving polymers. In this research work, an acidic ionic liquid, i.e. 1-(carboxy methyl)pyrridinium chloride, was synthesized and investigated for its potential to dissolve cellulose, chitosan and chitin. First, the optimum weight fraction of IL/water was determined to be 60/40 wt.% according to the effective dissolution of cellulose, chitosan and chitin. The synthesized IL exhibits more favorable interplay with water which is evidenced by higher water content in IL/water mixture. This is in contrast to previously examined ILs and demonstrates the less dependency of dissolution process to water content in cellulose and IL. Under these conditions, the reduced solution viscosity could account for a reduction in dissolution costs. Then, the dissolved cellulose, chitosan and chitin were regenerated in water or ethanol and then characterized with respect to their properties.
