COAGULATION OF BIOPOLYMERS FROM IONIC LIQUID SOLUTIONS USING CO2

摘要

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.
