Choline hydrogen carbonate was reacted with the FFA present
in OODD for their conversion into choline carboxylates. Thereafter,
scCO2 extraction of the rest of the oil components from the choline
carboxylates was performed at 313 K and 15 MPa with a CO2 flow
rate of 2 ml min1
for 2 h. These conditions were chosen based on
the results obtained from the model mixture experiments.
