  • Patent number: 4348422
    Abstract: A process for the direct decaffeination of aqueous coffee extract solutions by contacting the surface of a thin film of an aqueous coffee extract solution with carbon dioxide under supercritical conditions of temperature and pressure to thereby remove the caffeine into the CO.sub.2 and directly recover the aqueous coffee extract solution substantially free from caffeine. The contacting of the aqueous coffee extract solution and the CO.sub.2 is preferably effected by passing the aqueous coffee extract solution downwardly through a packed column, while passing the CO.sub.2 upwardly in countercurrent contact therewith.

  • Patent number: 4076757
    Abstract: A series of mono, bi and tricarbocyclic compounds, most of which have olefinic unsaturation in the ring, which may or may not have substituents thereon. While the bi and tricyclic rings may be unsubstituted, these compounds which have olefinic unsaturation, particularly multiple olefinic unsaturation, are polymerizable and copolymerizable in known polymerization systems. They are particularly good crosslinking agents. These compounds are further useful in the sense that they can be cleaved oxidatively, to corresponding carboxylic acids, aldehydes and/or alcohols which have known utility in the plasticizer and detergent arts. The compounds which do not have olefinic unsaturation can also be oxidatively cleaved to produce oxygenated, e.g., acid, alcohol or aldehyde, compounds having known utility.
