Abstract:
Disclosed herein are processes for providing a biopolymer from a biomass or source of chitin using ionic liquids. The processes involve contacting a biomass or source of chitin with an ionic liquid to produce a biopolymer comprising solution and precipitating the biopolymer from the solution with supercritical CO2, gaseous CO2, or combinations thereof.
