【 摘 要 】

An imidazoline quaternary corrosion inhibitor suitable for oilfield was synthesized. Oleic acid, diethylene triamine, and quaternary ammonium reagents were used in the experiment. The dimethylbenzene was used as water carrying agent. Under the experimental conditions, the inhibition rate of the synthesized corrosion inhibitor in hydrochloric acid can reach to 99.113%. Infrared spectrometer was used for the imidazoline corrosion inhibitor intermediates and the quaternary ammonium and the structures were characterized. The complex with sodium sulfite, potassium iodide, sodium lauryl sulfate, potassium pyroantimonate, glycerol, OP-10, propargyl alcohol, isopropyl alcohol and thiourea were researched. The better mixtures with good synergy were selected and the best ratios were obtained.
