Modification of chitin particles with chloride ionic liquids

Małgorzata Maria Jaworska , Andrzej Górak


Chitin cannot be dissolved in conventional solvents due to the inter- and intra-sheet network of hydrogen bonds in the crystalline regions. Because of their solubilizing effect for cellulose, some ionic liquids have been suggested as possible solvents for chitin. Six ionic liquids having Cl� as the anion have been tested, five of these with cations based on the 3-methyl-imidazolium entity and differing in the structure of the 1-alkyl substituent ([Amim], [Emim], [Bmim], [Hmim], [Momim]) and the sixth, ([Bdmim]), with the 1-butyl-2,3-dimethyl-imidazolium cation. Chitin was regenerated from the ionic liquids with water or ethanol. The particle size of chitin was not changed after precipitation with water except those from [Emim][Cl] and [Bmim][Cl]. In addition SEM analysis showed an increase in particle porosity after regeneration of chitin with water. The measured solubility of chitin was o5% for all the ILs tested.
