Acetone-based cellulose solvent

Macromol Rapid Commun. 2014 Aug;35(16):1419-22. doi: 10.1002/marc.201400211. Epub 2014 Jun 13.


Acetone containing tetraalkylammonium chloride is found to be an efficient solvent for cellulose. The addition of an amount of 10 mol% (based on acetone) of well-soluble salt triethyloctylammonium chloride (Et3 OctN Cl) adjusts the solvent's properties (increases the polarity) to promote cellulose dissolution. Cellulose solutions in acetone/Et3 OctN Cl have the lowest viscosity reported for comparable aprotic solutions making it a promising system for shaping processes and homogeneous chemical modification of the biopolymer. Recovery of the polymer and recycling of the solvent components can be easily achieved.

Keywords: acetone; cellulose solvent; dissolution; quaternary ammonium salt.
