Abstract

This paper reports the method of synthesis and the results of the investigation of the components of a solid corrosion inhibitor intended for the protection of equipment of gas-condensate and oil wells. 1-Amidohydroxystearate-diethyldiamine-2-hydroxystearylimidazoline was synthesized by the interaction of hydroxystearic acid with triethyltetramine. By chemical transformation of pork fat with triethyltetramine, amidoamines of fatty acids were synthesized. The passage of the relevant chemical reactions was confirmed by the methods of infrared spectroscopy and gas chromatographic analysis. The gravimetric method was used to investigate the inhibitory properties of the synthesized substances with respect to 08 ps steel in a simulated corrosive medium. The optimal ratio between 1-amidohydroxystearate-diethyldiamine-2-hydroxystearylimidazoline and amidoamines of fatty acids in the composition of the corrosion inhibitor in a new commercial form (solid) was established. It was shown that the use of amidoamines of fatty acids as part of a corrosion inhibitor helps to reduce its softening temperature and improve plasticity and solubility.

石油天然气工业固体缓蚀剂的活性物质

本文报告了一种用于保护天然气凝析油井和油井设备的固体缓蚀剂的合成方法和成分研究结果。1-Amidohydroxystearate-diethyldiamine-2-hydroxystearylimidazoline 是通过羟基硬脂酸与三乙基四胺的相互作用合成的。通过猪脂肪与三乙基四胺的化学转化，合成了脂肪酸的氨基胺。红外光谱和气相色谱分析方法证实了相关化学反应的通过性。使用重量法研究了合成物质在模拟腐蚀介质中对 08 ps 钢的抑制特性。确定了 1-氨基羟基硬脂酸酯-二乙基二胺-2-羟基硬脂酰咪唑啉和脂肪酸氨基胺在新型商业形式（固体）缓蚀剂成分中的最佳比例。研究表明，使用脂肪酸氨基胺作为缓蚀剂的一部分，有助于降低缓蚀剂的软化温度，改善可塑性和溶解性。

期刊介绍： Voprosy Khimii i Khimicheskoi Tekhnologii (Issues of Chemistry and Chemical Technology) is published bimonthly by the Ukrainian State University of Chemical Technology and accepts Ukrainian- or English language high-quality original articles and reviews concerning various fields of research in chemistry and chemical engineering. Our unusual title “Voprosy khimii i khimicheskoi tekhnologii” originates from the transliterated initial Russian title “Issues of Chemistry and Chemical Technology“. The fact of the matter is that Voprosy khimii i khimicheskoi tekhnologii was founded in 1965 as a scientific journal mainly for Russian-reading and Russian-speaking readership when «the Iron Curtain» existed. Since 1991, after Ukraine declared its independence, our Journal began to publish the articles in Ukrainian and English. Multilingualism is our established tradition. We remember and cherish our traditions, but we follow the latest trends in modern science. Papers that are multidisciplinary or address new or emerging areas of chemistry and chemical engineering are particularly encouraged. Thus, the scope is dynamic. It includes but is not limited to the traditional areas of general, inorganic, organic, analytical, physical chemistry and electrochemistry, as well as all conventional areas of chemical engineering (chemistry of high molecular compounds, technology of inorganic and organic substances, processing of combustible minerals, chemical technology of silicates, processes and apparatus of chemical productions, etc.). The Journal publishes papers dealing with newer interdisciplinary areas such as materials science, nano-science, catalysis, computational and theoretical chemistry, surface phenomenon and colloidal systems, environmental chemistry, green chemistry.
