Acrylate and Methacrylate Guanidine-Ionic Liquids for Dissolution of Cellulose

Abstract

It was shown for the first time that guanidine acrylate and methacrylate can act as ionic liquids for direct dissolution of cellulose (the solubility of dialdehyde cellulose is 27 % at the temperature of 60 °C). The conditions for the use of new ionic liquids as a dialdehyde cellulose solvent are found out: the temperature (60 °C), concentration of aqueous solution of acrylate (methacrylate) guanidine (1 mol/L).
