title: Reversible and non-reactive cellulose separations from ionic liquid mixtures with compressed carbon dioxide.
abstract: A novel physical (non-reactive) separation of cellulose from an ionic liquid (IL)/cosolvent mixture by compressed carbon dioxide is presented. The precipitation is completely reversible and rapid within small changes of pressure i.e. liquid phase CO2 composition. High pressure phase equilibrium, high pressure NMR, and solid state NMR have been utilized to understand the separation phenomena.
