  We have designed a general, inexpensive, and versatile method for the synthesis of (1H-benzo[d]imidazol-2-yl)(phenyl)methanone and the formation of C–N bonds via an aromatic aldehyde and o-phenylenediamine. In the presence of N,N-dimethylformamide/sulfur, (1H-benzo[d]imidazol-2-yl)(phenyl)methanone was obtained; however, in the absence of sulfur, quinoxaline was obtained in 1,4-dioxane. A wide range

  我们设计了一种通用，廉价且通用的方法，用于合成（1 H-苯并[ d ]咪唑-2-基）（苯基）甲酮并通过芳香醛和邻苯二胺形成C–N键。在N，N-二甲基甲酰胺/硫的存在下，得到（1H-苯并[ d ]咪唑-2-基）（苯基）甲酮。然而，在不存在硫的情况下，在1,4-二恶烷中获得了喹喔啉。在温和的条件下获得了广泛的喹喔啉和（1 H-苯并[ d ]咪唑-2-基）（苯基）亚甲酮。

  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.

  本公开涉及使用苯并咪唑来减少腐蚀的组合物和方法。该方法可以包括向与金属表面接触的水系中添加苯并咪唑和卤素。卤素可以是溴、碘或其任何组合。在某些情况下，添加卤素可能是可选的，具体取决于苯并咪唑环上的取代基。还公开了包括苯并咪唑、可选的卤素（具体取决于苯并咪唑环上的取代基）和可选的卤素稳定剂的组合物。

  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.
