In this paper, four quinoline quaternary ammonium salts were synthesized using quaternization reaction, which benzyl quinolion (BQL), naphthylmethyl quinolinium chloride (NQL), benzyl-8-hydroxy (BHQ) and 8-hydroxy (NHQ). The corrosion inhibition properties of the derivatives as inhibitors on P110 steel in 20% HCl solution at 60°C different concentrations investigated by weight loss electrochemical measurements. results showed that concentration inhibitor increases, rate decreased efficiency...
Based on corrosion thermodynamics and kinetics, considering the multi-field coupling effects of fluid flow, electrochemical reaction mass transfer process, a new prediction mechanistic model was proposed by introducing influence factor product film diffusion coefficient ion transfer, which is based CO2 Nesic et al. The temperature, flow rate pH value behavior 20# steel studied orthogonal tests. Scanning electron microscopy (SEM) energy spectrum analysis (EDS) used to analyze surface cross...
