Dendrimer based inhibitors for carbon steel has good performance.

Dendrimer based inhibitors for carbon steel has good performance.
Composite corrosion inhibitor is prepared by dendrimer and soluble silicates, adding the composite corrosion inhibitor to the acetic acid solution to be treated, it can well suppress the corrosion of carbon steel in contact with acetic acid solution, especially can suppress process water in the methanol to olefins process, the corrosion inhibition effect is good and would not adversely affect the process, which is better than ordinary phosphorus corrosion inhibitor. Steady play of silicate corrosion capability depends on whether the solution is to maintain a high concentration of the silicate. Using polypropylene copolymer and sulfonate copolymeras as stabilizer for silicic acid, the result is not good, and leads to the inhibition effect reduced. Using dendrimer as scale inhibitors, they can form a good suppression capability to colloidal silica under acidic conditions and maintain a high concentration of silicate in the acetic acid solution that can ensure excellent corrosion effect.
