Abstract: A process for extracting a botanical organic compound from cannabis with subcritical liquid carbon dioxide includes providing a pressurizable extraction vessel. The cannabis is placed within the pressurizable extraction vessel, whereupon the extraction vessel is filled with liquid carbon dioxide under subcritical conditions. The cannabis is then allowed to be in contact with the subcritical liquid carbon dioxide for a selected period of time so as to extract at least a portion of the botanical organic compounds from the cannabis into the subcritical liquid carbon dioxide. The subcritical liquid carbon dioxide containing the botanical organic compound is then removed from the extraction vessel, and the liquid carbon dioxide is separated from the botanical organic compound.

Abstract: A process is disclosed for extracting cannabinoids from plant materials. The process comprises providing a pressurizable extraction vessel having a rotatable drum with baffles, along with providing a solvent permeable filter bag. The plant material is placed within the filter bag, and the filter bag containing the plant material is placed within the extraction vessel. The extraction vessel is then filled with subcritical liquid carbon dioxide and rotated to so that the plant material is in contact with the liquid carbon dioxide. After a selected period of time, the liquid carbon dioxide solvent containing the cannabinoid extracted from the plant material is removed from the vessel, and sent to a separator. The separator separates the cannabinoid from the liquid carbon dioxide solvent.

Abstract: A method of forming a machining spray for treating a surface of a substrate during a machining process includes providing a first component containing solid carbon dioxide particles. A second provided component is derived from an inert gas having a temperature range from 305 K to about 477 K prior to being mixed with the solid carbon dioxide particles. The first component and the second component are combined to form the cryogenic fluid composition prior to contacting the substrate. An optional additive may be mixed with the solid carbon dioxide particles or the inert gas. The cryogenic fluid composition exhibits synergistically enhanced physicochemical properties of each component not observed prior to the combination thereof, wherein the fluid imparts enhanced cooling, heating or lubrication effects.
