Halogen Containing Patents (Class 568/74)
-
Patent number: 11692150Abstract: The present invention provides a class of halogen-containing synthetic base oils, and preparation method and use thereof. The synthetic base oils have introduced with halogen, especially fluorine, wherein the dipole motion of the halogen groups results in dipole interaction between the dipoles of other components and the base oil molecules of dipole-dipole and dipole-induced halogen (especially fluorine), and the interaction force is stronger and more localized than the dispersion force between the molecules of pure hydrocarbon synthetic oils, and thus the performance of the base oils is directly affected. It solved the problem of oil solubility of pure hydrocarbon synthetic oils, and also improved the properties of oxidation resistance and thermal stability.Type: GrantFiled: August 1, 2018Date of Patent: July 4, 2023Inventors: Dongchu Wei, Binbin Liu, Bing Li

Patent number: 7087661Abstract: The present invention provides compounds and materials that reduce the accumulation of microorganisms a surface, by interfering with the attachment of the organisms to the surface. The compounds and materials are thus useful in preventing the formation of biofilms on surfaces in health-related environments. By preventing the formation of biofilms, the compounds formulated according to the present invention can be used in the fabrication of grafts, implants, medical devices in order to prevent infection thereof. The compounds formulated according to the present invention display an additional anticoagulant property, permitting their use in settings where decrease in blood coagulability is desirable.Type: GrantFiled: September 23, 1999Date of Patent: August 8, 2006Assignee: Cernofina, LLCInventors: Randall S.
