用于油气集输缓蚀剂及其制备方法
摘要：
本发明公开了一种用于油气集输缓蚀剂，属于防腐技术领域。以重量百分比计，它由以下组分制成：脂肪酸10～40％；多乙烯多胺10～30％；硼酸0.5～6％；季铵化试剂5～30％；复配体5～15％；有机溶剂10～25％。本发明通过先合成季铵盐化咪唑啉化合物，然后将复配体加入至季铵盐化咪唑啉化合物中，形成了缓蚀剂复合物。该复合物中添加的十二烷基硫酸钠、十二烷基苯磺酸钠、碘化钠、溴化钠的复配体，可以在季铵盐化咪唑啉化合物的基础上增加缓蚀效果，提高缓释率，同时十二烷基硫酸钠、十二烷基苯磺酸钠属于无毒的生物降解性的表面活性剂，还起到一定的去油污作用。本发明还公开了上述缓蚀剂的制备方法。
摘要（英）：

The invention discloses corrosion inhibitor for oil and gas gathering and transferring, and belongs to the technical field of corrosion prevention. The corrosion inhibitor is prepared from, by weight, 10-40% of fatty acid, 10-30% of polyethylene polyamine, 0.5-6% of boric acid, 5-30% of quaternization agent, 5-15% of complex and 10-25% of organic solvent. A quaternized imidazoline compound is synthesized first, the complex is added into the quaternized imidazoline compound to form a corrosion inhibitor compound. As the complex of lauryl sodium sulfate, sodium dodecyl benzene sulfonate, sodium iodide and sodium bromide is added into the compound, the corrosion inhibition effect is improved on the basis of the quaternized imidazoline compound, the corrosion inhibiting rate is increased, and meanwhile lauryl sodium sulfate and sodium dodecyl benzene sulfonate belongs to nontoxic biodegradable surfactant and have a certain effect of removing oil dirty. The invention further discloses a preparing method of the corrosion inhibitor.
