CORROSION INHIBITORS FOR OILFIELD APPLICATIONS |
摘要 |
<p>Imidazoline dimer-type compounds which are prepared by the reaction of dimer fatty acid and a dialkylene triamine, such as diethylenetriamine (DETA), are useful for corrosion inhibition in water-containing fluids contacting metal, particularly fluids containing CO2 and/or H2S. When the reaction is conducted with molar excess of the polyamine, the resulting imidazoline dimer or oligomer is surprisingly more effective at corrosion inhibition than conventional monomeric imidazoline. Also unexpected is the better water solubility of the reaction product as compared with the conventional monomeric imidazoline.</p> |
