Preparation Of DCHA Volatile Corrosion Inhibitor
The invention syngas corrosion inhibitor by in situ intercalated synthesis of raw materials, auxiliary insertion montmorillonite silicate layers in situ synthesis, using synthetic exothermic overcomes the coulomb force between the silicate layers, stripping the silicate layers and gas phase corrosion inhibitors to nanoscale phase composition, with uniform structure and fine granularity of vapor phase corrosion inhibitor, improved the evaporation capacity of the gas phase corrosion inhibitors And corrosion inhibition performance.
A vapor phase corrosion inhibitor preparation method, including the following steps :
a. Dispersing montmorillonite in deionized water, beating, stirring, and then taking the suspension of the solution to add morpholine, heating the solution to evaporate and precipitate crystals.
b. Add formaldehyde to the solution in Step a and let it stand; add dicyclohexylamine and let it stand; then add the mixed solution of benzoic acid and acetone to the solution and let it stand to generate white slurry. Finally, the slurry is dispersed in deionized water, filtered and dried by air at 80℃ to obtain the target product.
