| Abstract: | Compound YHX-4 was prepared and its corrosion inhibition properties were studied under the CO2/H2S coexistence conditions. Results indicated that the optimum conditions for synthesizing imidazoline quaternary-ammonium-salts corrosion inhibitor (YHX-3) were:n(oleic acid)∶n(diethylenetriamine)∶n (thiourea)∶n (benzylchloride)=1:1.4∶1∶1.2,the cyclization reaction lasted for 8 h at the highest temperature of 220 ℃, and then quaternized for 3 h at 90 ℃. The structure of the product was proved with infrared spectrum. Corrosion inhibitor YHX-4 was then composed of YHX-3 and other four self-made substances including HPOMAQ, BOZ, TEP and SA [m(YHX-3)∶m(BOZ)∶m(HPOMAQ)∶m(TEP)∶m(SA)=30∶8∶8∶3:1]. The efficiencies of its static and dynamic corrosion inhibition in the CO2/ H2S medium were more than 92% and 88%, respectively. |
