“…12 and Table 6. Tables 5 and 6 show that propargyl alcohol in hydrochloric acid solution gives an excellent performance in terms of protecting carbon steel, confirmed by research works presented in the literature [12][13][14][15]. This suggests that the adsorption capacity of propargyl alcohol molecules in metallic surfaces is owed to the -electrons that interact with the metallic surfaces and consequently is associated with the properties of triple bonds of the propargyl alcohol molecule (HCCCH 2 OH).…”

Abstract:The commercial hydrochloric acid obtained by synthetic processes or from chlorinated products of recoveries shows in its final chemical composition contaminants such as chlorine and organochlorides. In acid stimulation of oil wells, hydrochloric acid is used to increase the productivity of the well by dissolving calcareous rock. However, there is increasing concern about the action of these contaminants as they can cause damage to the reservoir rock or corrosion inhibitors act on reducing its performance in corrosion protection of carbon steel pipes through which the hydrochloric acid is injected into the rock. In order to evaluate the performance of propargyl alcohol as a corrosion inhibitor, laboratory tests were carried out with hydrochloric acid solutions at concentrations of 10% (mass%) and chlorine in quantities of 50 to 5,000 mg/L. Gravimetric and electrochemical techniques showed that carbon steel coupons showed a significant reduction in the ability of corrosion inhibitors when the acid concentration and the chlorine concentration were increased. It was also verified that increasing temperature increased the corrosion rate of the system, regardless of the concentration of the corrosion inhibitor. The results showed that propargyl alcohol is efficient as a corrosion inhibitor for mild steel in hydrochloric acid solution.

“…All inhibitors contains ÀCOOH group which may adsorb on the metal surface. Patr et al [35] and Quaraishi et al [36] were explained that the inhibitors inhibit corrosion of metal surface through their chlorine atom. Tri-, di-, and monochloro acetic acids are strong inhibitors than others because the chlorine atom is electron attracting group led to increase the ionization of COOH which adsorbed on metal.…”

The anodic corrosion of copper in presence of acetic acid derivatives were determined by measuring the limiting current. It is found that the rate of corrosion increased by decreasing H 3 PO 4 concentration and electrode height. The experimental results showed that the inhibition efficiency increased with increasing concentration of the investigated compounds at a fixed temperature, but decreases with increasing temperature. Values of activation energy indicate that the reaction is diffusion controlled. The isotherm Langmuir, Temkin, and Flory Huggins are applied. The values of free energy of adsorption (DG ads ) obtained indicate the spontaneous adsorption of the inhibitor. The overall mass transfer correlations under the present conditions have been obtained using dimensional analysis method. The results agreed with the previous studies of mass transfer to rotating cylinder in turbulent flow.At the end of the corrosion process the morphology of the specimens after experiment is monitored using scanning electron microscope (SEM). SEM examination of the copper surface revealed that these compounds inhibited copper from corrosion by adsorption on its surface to form protective film. The presence of these organic compounds adsorbed on the electrode surface was confirmed by SEM investigations.

ASTM A182 F51 duplex stainless steel with a 50:50 ratio of austenite to ferrite microstructure is a material used in mechanical engineering. Its uses include the manufacturing of equipment and components subject to acidification or acid stimulation for oil and gas industries. During acid stimulation or acidification, hydrochloric acid (HCl) solution with concentrations ranging from 5% to 28% (by volume) is injected into the limestone (CaCO 3) and dolomite (CaCO 3 •MgCO 3) reservoir rock to restore permeability and consequently increase oil well productivity. Therefore, it is important to use a corrosion inhibitor, such as propargyl alcohol, to prevent or inhibit the aggressive attack of HCl on duplex stainless steel. The present study evaluates the corrosion resistance of ASTM A182 F51 stainless steel using gravimetric (mass loss) and electrochemical (polarization) tests. Studies were completed with and without the addition of 500 and 1,000 mg/L propargyl alcohol in HCl solutions with concentrations of 10% and 15% (by volume) at temperatures of 25, 40 and 55 °C. The good protection by propargyl alcohol of duplex steel immersed in HCl is observed.
