Hazirda inki§af etmi§ sanaye ölkalarinin an aktual problemlarindan biri da metal avadanliqlarin, texnikanin, texniki qurgularin atmosfer korroziyasindan müda-fiasidir [1]. Bu problemin getdikca daha aktual olmagi atmosferin aqressiv kompo-nentlarla (H2S, CO2, SO2, SO3, NO2 va s.) 9irklanma saviyasinin artmasidir [2]. Bu baximdan atmosfer korroziyasindan müdafia ü9ün samarali konservasiya mayelarinin va sürtkülarinin yaradilmasi sahasinda geni§ tadqiqatlar aparilir [3-5]. Bela tadqiqatlar
sirasinda AMEA-nin Akad.Y.H. Mammad-aliyev adina neft-kimya proseslari institutunda son 25 ilda aparilan ugurlu i§lar da var [6-8 ].
Qeyd edak ki, Xazar hövzasi böyük neft va qaz ehtiyatlarina malikdir va Xazar danizinda va onun sahillarinda bir 9ox yataqlarda neft va qaz 9ixarilir. Digar tarafdan, Xazarda neft va neft mahsullari tranziti intensivla§ir. Bu baximdan, yüksak keyfiyyatli konservasiya mayelarinin yaradilmasi sahasinda geni§ tadqiqatlar aparilir.

Amidoamines of natural petroleum acids isolated out of Baku oil and aminoimidazoline, as well as complexes of aminoimidazolines with vegetable oils have been synthesized. Catalytic oxidation of sunflower oil has been carried out. On the basis of T-30, T-22 oil and synthesized substances, corrosion-preventing liquids have been produced and appropriate studies carried out to inquire into their protective properties in the hydrocamera, sea water and 0.001 % H2SO4 solution. Concentration of substances used as corrosion inhibitors in corrosion-preventing liquids is 10, 15, 20%, respectively. Both individually and compositionally, the inhibitors have been added to the mineral oils, and further to corrosion-preventing liquids. Appropriate studies revealed that the composition with aminoimidazoline synthesized on the basis of natural oil acids and diethylene triamine with acid of sunflower oil in ratio 1:1 with the addition of 10% composition to T-30 oil has the highest protective ability. Thus, the composition protects Steel-3 against atmospheric corrosion in hydrocamera, sea water and 0.001 % of the solution of H2SO4 within 287,165 and 162 days, respectively. Also, it found that when taking equal amounts (3.33%) of sunflower oil, C14 nitro compounds, as well as aminoimidazoline based on sunflower oil acids and PEPA in a ratio of 1: 1 has a synergistic effect.

Синтезированы амидоамины природных нефтяных кислот, выделенных из Бакинской нефти, аминоимидазолины, комплексы аминоимидазолинов с растительными маслами. Проведено каталитическое окисление подсолнечного масла. На основе масла Т-30, Т-22 и синтезированных веществ были приготовлены консервационные жидкости и проведены исследования их защитных
свойств в гидрокамере, морской воде и 0.001%-ом р-ре Н2Б04. Концентрация используемых веществ в качестве ингибиторов коррозии в консервационных жидкостях составляет соответственно 10, 15, 20%. Как по отдельности, так и в виде композиций ингибиторы были добавлены к минеральным маслам, а далее к консервационным жидкостям. На основе проведенных исследований было установлено, что наибольшей защитной способностью обладает композиция, приготовленная на основе аминоимидазолинов, синтезированных на базе природных нефтяных кислот, и диэтилентриамина с кислотой подсолнечного масла в соотношении 1:1 с добавлением 10%-ой композиции к маслу Т-30. Данная композиция защищает Сталь-3 от атмосферной коррозии в гидрокамере, морской воде и 0.001% растворе Н2Б04 в течение 287, 165 и 162 суток соответственно. Также было установлено, что при взятии в равных количествах (3.33%) подсолнечного масла, С14 нитросоединений, а также аминоимидазолина на основе кислот подсолнечного масла и ПЕПА в соотношении 1:1 наблюдается синергетический эффект. Ключевые слова: амидоамины природных нефтяных кислот, аминоимидазолины, ингибитор, консервационные жидкости, синергетический эффект, защита от коррозии.
