Patent number: 7459102Abstract: A corrosion inhibitor that includes several oxo-anion compositions useful for preventing the propagation of pit corrosion on aluminum and aluminum alloys. The oxo-anion compositions may include soluble polymeric oxidic acids comprising combinations of molybdenum, phosphorous, tungsten, and silicon. These compositions are useful as corrosion inhibitors in high-moisture, corrosive environments, such as radiators and cooling systems. For low-moisture environments, these oxo-anion compositions can be reacted with a counter-ion, such as various metals, including, but not limited to the rear earth metals, to form a soluble salt. The salt can then be adsorbed onto a carrier, such as paint pigments, which can then be applied to the surfaces of aluminum and aluminum alloys. These surface adsorbates then become sparingly soluble and are gradually released over time in the presence of an aqueous corrosive agent so as to prevent propagation of pit corrosion.Type: GrantFiled: March 18, 2004Date of Patent: December 2, 2008Assignee: The Boeing CompanyInventor: Martin W Kendig

Patent number: 7109261Abstract: Halogen-containing polymer compositions comprising a latent mercaptan-containing heat stabilizer composition substantially free from the offensive odor typically associated with mercaptans are protected during processing by the degradation products of the latent (i.e., blocked) mercaptan which include a free mercaptan. Other products of the degradation are believed to include carbocations of the blocking moiety which are stabilized by a molecular structure in which the electron deficiency is shared by several groups. The latent mercaptan may be the sole heat stabilizer additive but the free mercaptan released during processing may also synergize the activity of metal-based heat stabilizers such as metal salts and organometallic stabilizers such as organotin carboxylates and mercaptides in the polymer composition. The odor of primary mercaptan-containing heat stabilizers in halogenated polymer compositions is masked by a small amount of a latent mercaptan.Type: GrantFiled: September 8, 2003Date of Patent: September 19, 2006Assignee: Rohm and Haas CompanyInventors: Tod C. Duvall, Paul B. Adams, Gene K. Norris

Patent number: 6716370Abstract: A corrosion inhibitor is described which includes several supramolecular oxo-anion compositions useful for preventing the propagation of pit corrosion on aluminum and aluminum alloys. The oxo-anion compositions preferably include soluble polymeric oxidic acids comprising combinations of molybdenum, phosphorous, tungsten, and silicon. These compositions are useful as corrosion inhibitors in high-moisture, corrosive environments, such as radiators and cooling systems. For low-moisture environments, these oxo-anion compositions can be reacted with a counter-ion, such as various metals, including, but not limited to the rear earth metals, to form a soluble salt.

Patent number: 6602445Abstract: An additive to a flame reaction forms noncorrosive deposits on cooler metal surfaces, which deposits are more stable than Na2SO4 or K2SO4. By adding molybdenum salts to the flame, an alkali polymolybdate is produced on the cooler metal surface and corrosion is inhibited. Deposition appears to closely reflect the relative thermodynamic stabilities of these salts. The flame processes all chemical molybdenum salt precursors as equivalent sources of molybdenum. The level of molybdenum required is equal to 2 times or more that of the alkali on an atomic basis in the flame environment. The nature of the fuel purity and possible alkali reduction schemes invoked will control the actual quantity and mixing method of the additive. The additive may be directly mixed into the fuel or injected into the burned gas regions of the combustor.Type: GrantFiled: July 31, 2002Date of Patent: August 5, 2003Assignee: The Regents of the University of CaliforniaInventor: Keith Schofield
