  • ONE-POT HOMOGENEOUS PROCESS FOR THE LARGE SCALE MANUFACTURE OF 2-SUBSTITUTED BENZIMIDAZOLES
    Publication number: 20230053321
    Abstract: 2-substituted benzimidazoles and methods of preparing the same are disclosed. The compositions may include a compound or salt thereof, a strong acid, and a carboxylic acid. The compositions may exclude a polar aprotic solvent. The compositions may be used to inhibit corrosion of a metal surface in contact with an aqueous system, and provide enhanced protection against corrosion of metals in the aqueous system.

  • Process and method for reducing metal corrosion in water
    Patent number: 11572628
    Abstract: This disclosure relates to compositions and methods of reducing corrosion using benzimidazoles. The method may include adding a benzimidazole and a halogen to an aqueous system that is in contact with a metal surface. The halogen may be bromine, iodine, or any combination thereof. In some cases, adding the halogen may be optional depending on the substituents on the benzimidazole ring. Compositions are also disclosed that include a benzimidazole, optionally a halogen depending on the substituents on the benzimidazole ring, and optionally a halogen stabilizer.

  • METHOD OF MEASURING BENZIMIDAZOLE-BASED COMPOUNDS IN WATER
    Publication number: 20190271674
    Abstract: The present disclosure generally relates to methods of measuring benzimidazole-based corrosion inhibitors in cooling water. Methods may include withdrawing a sample of water containing a benzimidazole-based compound from an aqueous system and adding an acid to the sample of water and/or diluting with water. Methods may also include exposing the sample of water to light energy of a selected excitation wavelength and measuring an intensity of emitted light about a selected fluorescence emission wavelength. The intensity of the emitted light may be compared to a standard curve, which can be a plot of fluorescence emission intensity of the benzimidazole-based compound versus concentration of the benzimidazole-based compound. The concentration of the benzimidazole-based compound in the sample of water may be determined from the standard curve.
