Ultrasound‐assisted synthesis of substituted triazines and their corrosion inhibition behavior on N80 steel/acid interface

Abstract

The three substituted triazines were synthesized by ultrasound irradiation method and characterized by FTIR, 13 C NMR, and 1 H NMR. The corrosion inhibition behavior of the synthesized inhibitors on N80 steel in 15% HCl was studied using electrochemical analyses and weight loss methods. All three inhibitors exhibited excellent corrosion inhibition performance, and the best inhibition effect was shown by TZ-3 (93.2% at 800 mg/L). EIS measurements suggest that the corrosion inhibition process is a charge transfer controlled. The PDP results indicated that all the triazines are mixed-type inhibitors.Langmuir adsorption model is the best fit among the other tested isotherms.These molecules can act as promising acidizing corrosion inhibitors for the oil gas industry. FTIR, AFM, and UV-vis studies corroborate the adsorption of inhibitor molecules over the metal surface.

Synergistic effect of KI on the corrosion inhibition of a poly(diallylammonium chloride)-based cyclocopolymer containing bis-cationic motifs for mild steel corrosion in 20% formic acid

“…Fig. S7a † shows the Arrhenius plots from which the activation energy (E a ) for the dissolution of mild steel in the presence and absence of the inhibitor was calculated using eqn (7). The transition state plots (Fig.…”

“…However, corrosion inhibitors are hugely popular and in-demand approaches. [5][6][7] These substances signicantly reduce corrosion when added to a corrosive metal solution. Mild steel has enormous implications in industrial set-ups, and is used to construct machinery parts, pipelines, railways, automobile body parts, etc., owing to its favorable mechanical properties and affordable costs.…”

Greener approach toward synthesis of biologically active s‐Triazine (TCT) derivatives: A recent update

“…As depicted in Scheme 6, arylhexahydro‐1,3,5‐triazines (30) were synthesized by applying conditions of ultra‐sonication such as 250 W power for 280 s using 0.01 mol aryl amine (29) and an equimolar amount of formaldehyde (27) in water: ethanol solvent (60:40) [26].…”

Synthesis and Cytotoxic Activity of Hexahydro‐1,3,5‐triazine Derivatives through Ring Condensation

“…Comparing with traditional methods under conventional condition, this method is more convenient and easily controlled 20,21 . It can also felicitates reactions at ambient conditions that otherwise require higher temperature, pressure, or concentrations; to the best of our knowledge, the use of ultrasound has been extended to the synthesis of hexahydrotriazine derivatives, but they did not get enhanced yield for the reaction 22 …”
