“…The main functional groups in the AOCS include amide, amine, and sulfate groups. The peak at 3449 cm –1 indicates NH in the amide functional group, and the peak at 1641 cm –1 indicates the CO bond in this functional group . Amide functional group (−CONH 2 ) consists of a carbonyl group (CO) and an amine group (NH 2 ) that are connected to each other.…”

Natural surfactants are proposed as alternatives to chemical surfactants in enhanced oil recovery (EOR) process. This research involved the synthesis and analysis of a new green cationic surfactant extracted from avocado oil. We studied the properties of the surfactant solutions by conducting tests on the surface tension, emulsion formation, and compatibility with varying levels of salinity. After that, in order to study the efficiency of the surfactant, rudimentary tests of EOR, including surface and interfacial tension (IFT), contact angle, adsorption in porous medium, and two injection schemes of coherent surfactant and surfactant–alkali (SA) slug, were performed. The main functional groups in the avocado oil cationic surfactant (AOCS) include amide, amine, and sulfate groups, which were confirmed by related analyses. The estimated critical micelle concentration (CMC) of the avocado oil-based cationic surfactant (AOCS) was found to be approximately 725 ± 25 ppm (ppm). At this concentration, the interfacial tension between the surfactant and the oil surrounding medium was measured to be 0.316 millinewtons per meter (mN/m). Furthermore, the interfacial tension decreased to 0.063 and 0.035 mN/m under optimal salinity and alkalinity, respectively. The value of interfacial tension after about 35 days of the solution’s shelf life was out of the desired range. The contact angle decreased from 126.81 to 61.53° after 180 min, and the wettability of carbonate altered from oleophilic to hydrophilic by the surfactant. The AOCS was compatible with up to 60,000 ppm salinity, and after the injection of 2.5 PV, 6.2 wt % of it was adsorbed on the carbonate. The coherent injection of the AOCS increased the oil recovery by 25.6% to a total recovery of 80.1%. In another method, injecting a slug of SA with a volume equal to 0.5 pore volumes (PV) resulted in a significant increase in oil recovery, amounting to a 23.4% improvement, and the total recovery reached 77.7%.

“…The synthesis of the cationic surfactant from avocado oil was carried out in three steps using Tantawy et al’s method . In the first step, KOH was added to it for the saponification reaction and mixed gently for 24 h in a three-necked flask equipped with a nitrogen flow supplier, stirrer, and additional funnel at room temperature.…”

In the present study, we herein report the conductance behavior, effect of temperature, and chain-length of two environmentally friendly imidazolium cationic capric and stearic surfactants. The conductance behavior has been carried out in aqueous solvent (H 2 O) at four different temperatures such as 24 °C, 29 °C, 34 °C, and 39 °C. The normal micelles were formed in an aqueous solvent and critical micelle concentration (CMC) can be estimated through conductivity parameters. The expected dependency of the CMC on the alkyl chain length of the 3-(2-(decanoyloxy)ethyl)-1-methyl-1H-imidazol-3-ium-bromide and 3-(2-(octadecanoyloxy)ethyl)-1-methyl-1H-imidazol-3-ium-bromide was demonstrated. It was observed that the graphs of molar conduct activity v/s square root were not linear, which specifies that the synthesized surfactants behave as weak electrolytes in the dilute solutions. The electrochemical characterization of capric and stearic surfactant modified SPCE was studied in 1mM K 3 FeCN 6 solution. The CS/SPCE and SS/SPCE were shown elevated sensitivity, high stability, and excellent conductivity. Moreover, the antimicrobial behaviors of the synthesized imidazolium cationic surfactants versus various microbial strains were evaluated. Results showed that capric surfactant demonstrated high antibacterial activity against Escherichia coli (MIC > 31.5 μg/mL).

Для боротьби з корозією використовують корозійностійкі сплави, що вимагає великих затрат і не є достатньо надійним засобом, та інгібітори корозії, які потрібно постійно вдосконалювати для підвищення їх ефектив ності та зменшення собівартості. Оскільки корозія характеризується руйнуванням мате ріалу внаслідок взаємодії із навколишнім сере довищем, то одним із доцільних методів її мінімізації є використання інгібіторів. Тому актуальним завданням охорони навколишньо го середовища та економічного розвитку країни є розробка ефективних засобів захисту металів від корозії. Отриманий інгібітор АС2 (розчин суміші 2алкілімідазолінів в метанолі) досить ефективно захищає сталь від корозії у водно нафтових сумішах при високих концентра ціях мінеральних солей у воді. Ефективність інгібітору практично не залежить від спів відношення об'ємів нафти та концентрованих водних розчинів хлориду натрію. При викорис танні інгібітору при концентрації 50 мг/дм 3 ступінь захисту сталі від корозії перевищував 90 %. Пов'язано це з тим, що захист сталі від корозії відбувається за рахунок сорбції імідазо лінових складових на поверхні металу та сорб ції органічних складових нафти на гідрофобних алкільних групах 2алкілімідазолінів. При цьому гідрофобізація поверхні металу відбувається в присутності незначних кількостей нафти. Показано, що у суміші, що містила 200 см 3 3 % розчину хлориду натрію та 800 см 3 нафти, при концентрації оцтової кислоти відповід но 0,5 та 3,0 г/дм 3 , при температурі 80 °С при дозі інгібітору 15-50 мг/дм 3 , ефективність була 72-92 %. Це дозволяє вирішити проблему раціонального природокористування та забез печує перехід до використання екологічно без печних енергоефективних технологій Ключові слова: інгібітор корозії, 2алкілімі дазолін,воднонафтова суміш, швидкість коро зії сталі, ступінь захисту від корозії
