Conclusions

Supercritical fluid extraction can be a clean alternative to liquid solvent extraction both for analytical sample preparation and for production scale, because environmentally friendly solvents such as carbon dioxide can be used instead of organic solvents. Some applications are found to be more successful than others. It requires more expensive equipment and a greater commitment to process development than liquid extraction. Nevertheless, it is being applied in specific areas, such as for polymer additives in analytical chemistry and as a method for obtaining valuable compounds from plants on a process scale.
