Among other things, phase diagrams help us predict those
conditions under which a substance will exist as a supercritical
fluid. Supercritical CO2 is especially useful as it is very
effective at dissolving nonpolar oils which constitute many of the
flavouring or odor-causing compounds in foods. For example, food
companies use supercritical CO2 to extract caffeine from
coffee.
a) Use the following data to label the following points on the
phase diagram for CO2: Triple point -57°C, 5.1 atm, Normal
sublimation...
