Ionic liquids as starch plasticizers or solvents (in English)

Polimery 2011, No 11/12, 861

DOI: dx.doi.org/10.14314/polimery.2011.861


The article presents results of application of ionic liquids {1-allyl-3-methylimidazolium chloride ([AMIM]Cl) as well as deep eutectic solvents: choline chloride/urea, choline chloride/citric acid, choline chloride/succinic acid} as plasticizers and solvents for potato starch. Rheometric measurements and morphology changes of thermoplasticized starch/ionic liquid systems and solubility tests for 5 wt. % starch solutions in ionic liquids have been performed. Dry starch was dissolved in ionic liquids at high temperatures (80—135 °C). [AMIM]Cl, choline chloride/urea and choline chloride (for moisturized starch) displayed best plasticizing abilities.

Key words: starch, ionic liquid, deep eutectic solvent, choline chloride, plasticizer, solvent
