The rate of extraction of tnacylglycerols with supercntical carbon dioxide can be greatly enhanced by raising the pressure of the fluid to 600 bar, or higher, and its temperature to 60Β°C, or higher. Both the amount of carbon dioxide and the time required for complete extraction are reduced at such h

## Abstract By means of the negative solvatochromic betaine dyes 1a, b, the UV/Visβspectroscopically derived empirical solvent polarity parameter __E__~T~(30) for supercritical carbon dioxide (scβCO~2~) was determined in the temperature and pressure ranges 40β80Β°C and 150β550 bar, respectively.
