New ionic liquids for modification of chitin particles

Małgorzata Maria Jaworska , Andrzej Górak

Abstract

Chitin particles are chemically and mechanically stable due to the strong inter- and intra-sheet network of hydrogen bonds and the large number of crystalline regions. Thus, it is difficult to make any modification of the chitin particles themselves. Therefore, new solvents which can modify the structure of chitin particles are being sought. This work presents the influence of unreported ionic liquids (ILs) containing the TCB anion on chitin: three of them contained the imidazolium ring, ([Im], [Dmim], [EOHmim]) and another three contained the pyridinum ring ([Pyr], [EOHpyr], [POHpyr]). Chitin did not dissolve in any of the tested ILs but the ILs were able to modify the structure (porosity and corrugation) of chitin particles. It has also been shown that [EOHpyr][TCB] caused the degradation of chitin particles. The degradation process strongly depends on temperature and the time of interaction; choosing proper conditions, particles with a narrow particle size distribution could be obtained.
