The inhibition performance of a novel benzenesulfonamide-based benzoxazine compound in the corrosion of X60 carbon steel in an acidizing environment

Abstract

The inhibition performance of a novel benzenesulfonamide-based benzoxazine compound in the corrosion of X60 carbon steel an acidizing environment has been examined including some highly electronegative atoms.

WITHDRAWN: Anticorrosive concert of expired drug acts as novel and potent inhibitor for deterioration of Low carbon steel in acidic Environment

“…This corrosion should be avoided or controlled otherwise it destroy the unique properties of low carbon steel. In India the cost of scale wastes from the industries is 26.1 billion USD, it is equal to 2.4 % of total GDP [1--9], the different types of heterocyclic organic compounds containing N, O, S and P molecules has been noted as corrosion inhibitors, The speci c was adsorbed on the low carbon steel surface and removed the metal's corrosion active sites, [10][11][12][13][14][15][16][17][18][19][20][21][22]. The following three major factors in uence inhibitor adsorption: metal type and nature, chemical structure of the inhibitor molecule, and medium of the metal present.…”

Efficient corrosion inhibition by sugarcane purple rind extract for carbon steel in HCl solution: mechanism analyses by experimental and in silico insights

“… 35 Furthermore, the best fit of the Langmuir model also reveals that the active sites on the metal surface are energetically equivalent, and the adsorption of SPRE follows monolayer adsorption. 47 K ads provides the adsorption strength for the inhibitor on the metal surface, which can be derived from the intercept of the fitted lines in Fig. 12a .…”

Experimental and theoretical study of tetraphenylethylene-based dicationic compounds for corrosion inhibition of steel and brass in an acidic medium

“…Whereas the interaction associated with charge sharing or charge transfer between the inhibitor and metal surface can be characterized as chemisorption if the value of DG o ads is around À40 kJ mol À1 or more negative. 9,13,29 The calculated results of TPE-2NH 3 Á2SCN on 20# steel surface for (3) and ( 4) are c/y = 1.0075 c + 5.1748 Â 10 À6 , K ads = 1.9324 Â 10 5 L mol À1 and DG o ads = À44.84 kJ mol À1 , respectively (Fig. 10(a)).…”

“…The chemical composition of the H62 brass coupon is listed in Table 2. 1 H NMR and 13 C NMR spectra were recorded on a Bruker Avance 400 MHz instrument. High-resolution mass spectra (HRMS, ESI) were obtained on a Bruker Solarix-FT-ICR MS instrument.…”
