Imidazoline sustained-release agents are a common chemical reagent used in many industries. Today, I will introduce the product characteristics of imidazoline corrosion inhibitors to you.
Imidazoline type corrosion inhibitor is a compound containing five membered heterocycles. Due to its simple preparation method, easy availability of raw materials, high efficiency, and low environmental pollution, it is widely used in oil and gas well extraction and transportation, especially for the corrosion inhibition effect containing CO2 in the system. In an acidic system, the empty orbitals of nitrogen atoms and iron atoms in imidazoline type corrosion inhibitors form coordination bonds and adsorb on the surface of the matrix, forming a dense single molecule adsorption film on the surface of the matrix. This chemical adsorption changes the charge state and interface properties of the metal surface, increases the reaction activation energy required for anodic Fe oxidation, and also changes the redox potential of hydrogen ions, reducing the corrosion rate of the material, The corrosion inhibition effect of imidazoline inhibitor increases with the increase of π electron density in the imidazole ring.
