Abstract:

The mixed ionic liquid solvent N-methy-N-allylmorpholine chloride [AMMor]Cl/1-allyl-3-methylimidazolium chloride [AMIM]Cl can dissolve cellulose effectively. We surveyed the influence of the dissolution time and temperature to the dissolution properties. The chemical construction and thermostability of regenerated cellulose from the [AMMor]Cl/[AMIM]Cl were investigated with Fourier transform infrared(FTIR) spectroscopy, thermogravimetry(TG) and X-ray diffraction(XRD) measurements. Results show that the solubility cellulose in [AMMor]Cl/[AMIM]Cl is better than [AMIM]Cl under the same conditions. The cellulose samples without any pretreatment were readily dissolved in [AMMor]Cl/[AMIM]Cl in a relatively short time. In the course of dissolution, no other derivatizing reaction occurred and degrades slightly.
