As illustrated in the above graph, CO2 reaches its supercritical state at a pressure of 1071psi and 31 degrees celsius. Once this point has been reached, CO2 is no longer in its gaseous state and converts into a supercritical fluid. At this point, the supercritical CO2 acts similar to a liquid solvent such as ethanol.

19/6/2020, · When CO2 in a solid state hits temperatures above 17°C and pressure, above 1,000 psi,, it begins to sublimate, passing from a solid state directly to a gas state. In doing so, it becomes a powerful solvent when it hits the plant material, removing most of the terpenes and cannabinoids.

between 800-1500 psi., Supercritical, extraction It involves heating the, CO 2, to above 87 0F and pumping it above 1100 psi. Usually, this is between 6000-10000 psi., Supercritical, fluid, CO 2, can best be described as a dense fog when, CO 2, is used in a dense liquid state. Low-pressure, CO 2, is often the best method for producing high quality botanical extracts.

With the right combination of pressures and temperatures, the, supercritical CO2, will most easily dissolve the closest matching oil. It will also still dissolve other oils but at a slower rate. Terpenes, for example, are the flavor and aroma molecules. They are most easily dissolved at around 1500 psi and 110 degrees Fahrenheit. Above 2500 psi you start matching the more active oils. There is, however, a dead zone …
