“…SFE extracts were obtained from 10 g of plant material using an extraction apparatus with a fixed tubular extractor 9.4 cm in height and 2.13 cm internal diameter, as described by Esquível and Bernardo-Gil (1993). Briefly, CO 2 N45 grade (99.5% w/ w pure) was delivered at a flow rate of 0.3 kg/h from a standard cylinder, and was compressed to an extraction pressure of 12 or 18 MPa using an air-driven liquid pump after cooling.…”

“…In fact, many studies on extraction/fractionation of these unsaturated fatty acids and their derivatives with supercritical fluids have been made. [2][3][4][5][6][7][8][9][10] Due to nontoxicity and nonflammability, carbon dioxide is often employed as a supercritical solvent.…”

Measurements of Binary Diffusion Coefficient and Partition Ratio at Infinite Dilution for Linoleic Acid and Arachidonic Acid in Supercritical Carbon Dioxide

et al. 2003

The binary diffusion coefficient D 12 and partition ratio k were measured for two ω6 group compounds, linoleic acid and arachidonic acid, at infinite dilution in carbon dioxide at temperatures from 308.15 K to 343.15 K and pressures from 9 MPa to 30 MPa by a tracer response technique with a poly(ethylene glycol)-coated capillary column. The measured D 12 values were well represented by a correlation of D 12 /T versus CO 2 viscosity and by the Schmidt number correlation for each solute, and the k values were well represented as a function of temperature and CO 2 density. Partial molar volumes were also obtained from the k values.

“…Extraction and purification of the lipids by conventional methods, such as n-hexane extraction or vacuum distillation, presents some problems due to oxidation of the highly unsaturated fatty acids (4). The possibility of operating at relatively low temperature with a nonflammable solvent has made supercritical extraction (SCE) with CO 2 a very popular methodology for extraction of natural products (5)(6)(7)(8). This technique is of special interest in the food and cosmetics industries because carbon dioxide does not leave toxic residues.…”
