| Abstract: | N-alkyl benzoylamino bis-imidazoline as a corrosion inhibitor was synthesized with trimesic acid,metha-nol,alkyl amine and diethylenetriamine as the raw materials.The evaluation results showed that N-alkyl benzoyla-mino bis-imidazoline corrosion inhibitor had multi adsorption centers.Under the condition of 30 mg/L corrosion inhi-bitor,95℃,1.5 MPa CO2 and 300 r/min revolving speed,the corrosion inhibition rate was up to 93%for A3 steel slice. |
