  • Compositions useful for fluorine magnetic resonance imaging
    Patent number: 4913853
    Abstract: Water soluble, substantially nontoxic salts of compounds of the formula:CF.sub.3 Rwherein R is --SO.sub.3 H, --SO.sub.2 NH.sub.2 or --PO.sub.3 H.sub.2, are useful for obtaining fluorine magnetic resonance images of body organs and tissues. Illustrative salts of such compounds include sodium trifluoromethane sulfonate, N-methylglucaminium trifluoromethanesulfonate and N-methylglucaminium trifluoromethanesulfonamide.

    Inventor: George B. Hoey
  • Glycosyl triidobenzoic acid derivatives
    Patent number: 4321368
    Abstract: Ethylene is polymerized in the vapor phase in a stirred bed reactor. The reactor employed is vertically aligned and has a centrally positioned cored draft tube therein. An auger circulates polymer solids through the draft tube while coolant is circulated there through to remove the heat of polymerization.
