The construction of nanometre scale RuIIPdIIRuII π-conjugated molecular rods, Λ,Λ-1 and Δ,Δ-1, from enantiomerically pure building blocks, provides a method for obtaining enantio- and diastereo-merically pure RuII-based molecular architectures.

, (2021/06/02)
The invention discloses a dicationic benzimidazole corrosion inhibitor and a preparation method thereof. The preparation method comprises the following steps of: (1) carrying out acylation and cyclization reactions on 1, 2, 4, 5-tetraaminobenzene and thiophane-2-carboxylic acid-1, 1-dioxide to obtain a benzimidazole derivative; and (2) reacting the benzimidazole derivative with halogenated alkane to obtain the dicationic benzimidazole corrosion inhibitor. The corrosion inhibitor has a dicationic structure, so that the corrosion inhibitor has good solubility and strong adhesive force on a metal surface. In addition, the corrosion inhibitor has a plurality of alkane straight chains, and the hydrophobic end can directionally enter a corrosive medium, so that a hydrophobic layer is formed to repel the corrosive medium, and the corrosion inhibitor can be used as a corrosion inhibitor for carbon steel and copper and has a good corrosion inhibition effect.

The invention discloses a quinolyl benzimidazole corrosion inhibitor and a preparation method thereof.The preparation method comprises the steps that 1) carrying out cylation and cyclization reaction on 1,2,4,5-tetraaminobenzene and quinoline-4-carboxylic acid to obtain quinolyl benzimidazole; 2) carrying out chain extension on the quinolyl benzimidazole and tetramethylene diamine, and then carrying out quaternization reaction to obtain the quinolyl benzimidazole corrosion inhibitor. The corrosion inhibitor has high cation density and good solubility, nitrogen atoms and aromatic rings form conjugated pi bonds, and the adhesion force on the metal surface is high. In addition, the corrosion inhibitor has a plurality of alkane straight chains, and the hydrophobic end can directionally enter a corrosive medium, so that a hydrophobic layer is formed to repel the corrosive medium, and the corrosion inhibitor can be used as a corrosion inhibitor for carbon steel and copper and has a good corrosion inhibition effect.
