Synthesis of alkynyl alcohol derivatives and its corrosion inhibition on N80 steel in 5 M HCl
Alkynyl alcohol derivatives (N-14) were synthesized by 2-chloromethyl pyridine, propargyl alcohol and bromotetradecane and the structure was confirmed by 1H NMR, 13C NMR, MS and FTIR. The corrosion inhibition performance was evaluated by weight loss, Tafel polarization, EIS measurements and DFT quantum calculations. The results proved that N-14 effectively inhibited the acid corrosion of N80 steel. The corrosion inhibition of N-14 increased with its concentration and decreased with increasing temperature. A maximum of 99.56% inhibition efficiency was achieved using 5 × 10−5 mol/l of N-14 at 60°C. Thermodynamic parameters showed that the adsorption of N-14 on N80 steel is spontaneous and exothermic, conforming to Langmuir's adsorption. Electrochemical results showed that N-14 behaved as a mixed-type inhibitor. In addition, corrosion products produced on N80 steel surface were researched by SEM, XRD, UV and contact angle. At the same time, the corrosion inhibition mechanism was discussed.
