1. A method of precipitating a biomass, comprising:
- a. providing a composition comprising a biomass, an ionic liquid, and an amine, wherein the composition is substantially free from water; and
b. contacting the composition with carbon dioxide in an amount effective to react with the amine to form an amine carbamate effective to substantially precipitate the biomass from the composition, thereby forming a precipitated biomass.
