Another way to extract pure caffeine from coffee beans uses carbon dioxide. Carbon dioxide is a gas at atmospheric pressure and temperature, but if you raise the pressure and temperature, the gas changes into a supercritical liquid (like a cross between a liquid and a gas).

The first involves extracting the oils in coffee grounds. This is done by mixing the grounds with the solvent hexane and then cooking the mixture at 60°C for 1–2 hours to extract the oils. The hexane is evaporated to leave behind the oils. In the second step, methanol and a catalyst are added to create biodiesel. The oil in used coffee grounds can be extracted to make biofuel. The University of Nevada, conducted research back in 2008 using leftover coffee grounds from Starbucks. Using a relatively simple technique they were able to extract the oil from the grounds and then convert this into biodiesel. In order to reuse coffee grounds, the n-h ptane was used to extract the coffee oil from spent coffee grounds. Then the coffee oil and methanol were used to prepare biodiesel through transesterification. In addition, the coffee grounds after extraction of oil was used to make solid biofuels. Supercritical extraction was found to be the best technique for extracting coffee oil from spent coffee grounds due to the high solubility of oil in supercritical carbon dioxide, which works as good solvent in supercritical conditions.
