Patent number: 4284517Abstract: A method for the recovery of oil from an oil-containing subterranean formation by waterflooding employing as an injection medium an aqueous solution of an anionic polymeric surfactant formed by reacting a polymer including succinic anhydride moieties with a primary amine to provide a polymeric reaction product in which at least 20 mol percent of the anhydride moieties have been converted, by reaction with said amine, to succinimide or succinamide groups. The polymeric anionic surfactants of the invention exhibit good physical and chemical stability, are shear stable, are effective in maintaining the salt stability of other surfactants (such as petroleum sulfonates) and also function as viscosifiers, even in the presence of significant concentrations of divalent metal ions.Type: GrantFiled: October 26, 1978Date of Patent: August 18, 1981Assignee: Mobil Oil CorporationInventors: Catherine S. H. Chen, Edward W. Sheppard

Patent number: 4281086Abstract: Polymer bound multidentate complexes are prepared by reacting pendant benzyl chloride and benzyl iodide groups on a variety of polymer supports, including crosslinked polystyrene, with 3,3'-iminodiproprionitrile and reducing the nitrile groups by treatment with, for example, a boron hydride-tetrahydrofuran complex to form the amine. The amine is a precursor for other ligand systems; for example, the primary amine groups formed condense with an aldehyde or ketone to yield five coordinate Schiff base ligands. The polydentate amine ligand systems are useful for synthesis of chelating agents for sequestering metal ions from solution for purification or concentration purposes. Metal complexes of these ligands with manganese, iron, cobalt, nickel, copper, and zinc can be prepared which are useful as heterogeneous oxidation catalysts.Type: GrantFiled: May 12, 1980Date of Patent: July 28, 1981Assignee: The University of Illinois FoundationInventors: John H. Gaul, Jr., Russell S. Drago
