Investigation of cellulose dissolution in morpholinium-based solvents: impact of solvent structural features on cellulose dissolution.

ABSTRACT: A series of N-methylmorpholinium salts with varying N-alkyl chains and Cl^-, OAc^- and OH^- as counter ions have been synthesized and investigated for their ability to dissolve cellulose, aiming at elucidating solvent structural features affecting cellulose dissolution. Synthesis procedures have been developed to, to a high extent, rely on conversions in water and microwave-assisted reactions employing a reduced number of work-up steps and ion-exchange resins that can be regenerated. Water solutions of morpholinium hydroxides proved capable of dissolving cellulose, with those of them possessing alkyl chains longer than ethyl showing surprising dissolution ability at room-temperature. Morpholinium acetates behaved as ionic liquids, and were also c
