“…As mentioned in Table 7 IL-3MPyBr has a larger dipole moment value (17.1497 Debye) than IL–IL-1MPipBr, IL-1MPyrBr, IL-2MPyBr and IL-4MPyBr which recorded values as 17.1383, 15.9486, 15.8485 and 14.6848 Debye in order. Showing that the IL-3MPyBr's capacity to adhere to the surface of carbon steel and enhance inhibition is stronger 37 , 53 . Furthermore, the selection of inhibitory molecules to protect carbon steel's surface from corrosive environments is influenced by the molecular surface of the material 46 .…”

The challenge of corrosion posed as a result of acidic sittings is considered as a major industrial concern, wherein ionic liquids serve as crucial in addressing the corrosive impacts on metals. In this study, five selected cyclic ammonium based ionic liquids were synthesized; IL-1MPyrBr, IL-1MPipBr, IL-2PyBr, IL-3MPyBr and IL-4MPyBr and their chemical structures were characterized using a variety of spectroscopic techniques (FT-IR, IH-NMR, 13C-NMR, Elemental analysis and thermal gravimetric analysis (TGA). Their corrosion inhibition efficiency was studied on carbon steel in 1 M HCl via different concentrations at 298 K using chemical and electrochemical parameters (PDP and EIS). DFT quantum parameters were computed, and the noted results were in complete compatible with the experimental. The synthesized ILs recorded excellent inhibition on the carbon steel corrosion in acidic media with increasing efficiency by increasing the inhibitor concentrations from 20 to 100 ppm. Different cations in the synthesized ILs affect the anti-corrosion effect and IL-3MPyBr showed the highest inhibition (ηR); 96.12% using the lowest concentration. Kinetic and thermodynamic considerations were studied and illustrated.

“…The viscosity reduction of the blank test result was 28.5%. The effect of adding the ionic liquid to reduce the viscosity of heavy crude oil in catalytic aquathermolysis is interesting because an ionic liquid is environmentally friendly and has low vapor pressure [ 29 , 50 , 51 , 52 , 53 ]. Viscosity reduction values according to a series of experiments with different conditions are reported in Table S1 .…”

Heavy and extra heavy oil exploitation has attracted attention in the last few years because of the decline in the production of conventional crude oil. The high viscosity of heavy crude oil is the main challenge that obstructs its extraction. Consequently, catalytic aquathermolysis may be an effective solution to upgrade heavy crude oil to decrease its viscosity in reservoir conditions. In this regard, a series of acidic ionic liquids, 1-butyl-1H-imidazol-3-ium 4-dodecylbenzenesulfonate (IL-4), 1-decyl-1H-imidazol-3-ium 4-dodecylbenzenesulfonate (IL-10), and 1-hexadecyl-1H-imidazol-3-ium 4-dodecylbenzenesulfonate (IL-16), were utilized in the aquathermolysis of heavy crude oil. Of each IL, 0.09 wt % reduced the viscosity of the crude oil by 89%, 93.7%, and 94.3%, respectively, after the addition of 30% water at 175 °C. ILs with alkyl chains equal to 10 carbon atoms or more displayed greater activity in viscosity reduction than that of ILs with alkyl chains lower than 10 carbon atoms. The molecular weight and asphaltene content of the crude oil were decreased after catalytic aquathermolysis. The compositional analysis of the crude oil before and after catalytic aquathermolysis showed that the molar percentage of lighter molecules from tridecanes to isosanes was increased by 26–45%, while heavier molecules such as heptatriacontanes, octatriacontanes, nonatriacontanes, and tetracontanes disappeared. The rheological behavior of the crude oil before and after the catalytic aquathermolytic process was studied, and the viscosity of the crude oil sample was reduced strongly from 678, 29.7, and 23.4 cp to 71.8, 16.9, and 2.7 cp at 25, 50, and 75 °C, respectively. The used ILs upgraded the heavy crude oil at a relatively low temperature.

The inhibition effect of some of three different ionic liquids namely, IL-4, IL-8, and IL-10 on the corrosion behavior of C-steel immersed in 10% formation water (FW) solutions was examined at various concentrations and temperatures. Gravimetric measurements were complemented by surface investigation for some corroded C-steel samples using a scanning electron microscope (SCE). The inhibition efficiency, IE %, was found to increase with increasing the inhibitor concentration depending on its type while the rise in the solution temperature reduces the IE %. At optimum concentration of 500 the IE % reaches 52.21%, 45.83%, and 43.98%, successively, with IL10, IL8, and IL4. The presence of 0.02 M KI mixed with 500 ppm enhances the IE % to reach a maximum value of 90.5%, 85.6%, and 77.9%, successively, with IL10, IL8, and IL4. The existence of KI is considered an effective co-inhibitor that introduces a synergistic effect and stimulates the synergism. The inhibition mechanism was discussed through an adsorption process that follows the Langmuir model. The thermodynamic data suggests the existence of physisorption besides chemisorption processes on the surface of the C-steel surface.
