Corrosion inhibition efficiencies of heterocyclic, unsaturated (aromatic and nonaromatic) compounds (pyrimidines, benzothiazole derivatives, amino acids containing an aromatic part, pyridines, quinolines) were correlated with quantum chemical indices the respective molecules. Inhibition determined in acidic solutions 0.001 M or 0.01 inhibitor. Quantum calculations made by using Hückel method. The difference (Δ) between energy highest occupied lowest unoccupied molecular orbital was related...
Abstract Interaction of corrosion inhibitors with metal surfaces in acidic solutions was investigated using a nonlinear model encompassing the Langmuir adsorption isotherm. A regression equation, w...
Abstract The correlation between the molecular structure and inhibitor efficiency (Ei) of triamines was investigated. group-contribution approach adapted to account for Langmuir- Frumki...
Stöber silica particles having diameters of ca. 100 and 200 nm were prepared silylated using trimethylsilyl N,N-dimethylcarbamate, achieving a range surface coverage by groups varying the amounts silylating agent used. The efficacy silylation was characterized in terms hydrophobicity which assessed film balance investigations at water−air interfaces additionally imaging long- short-range structures particulate layers on mica supports Brewster-angle atomic force microscopies.
Abstract X-ray, electron and neutron-diffraction data have been used for the separation of g oo(r), od(r) dd(r) atom-atom pair-correlation functions liquid D2O. The experimental compared with those computed by molecular dynamics Monte Carlo methods.
Impedance spectra of carbon steel in the presence 1‐hydroxy‐ethane‐1,1‐diphosphonic acid (HEDP) has been investigated neutral solutions. The aim measurements was to study effect HEDP on corrosion as a function inhibitor concentration. An optimal concentration found be approximately 10−4 mol dm−3. A two‐time constant equivalent circuit model including phase element consistent with experimental data frequency range studied. system parameters obtained by nonlinear fit procedure are discussed...
The influence of calcium and zinc ions on the corrosion inhibition effect 1‐hydroxyethane‐1,1‐diphosphonic acid (HEDP) carbon steel has been investigated by electrochemical techniques, X‐ray photoelectron spectroscopy, atomic force microscopy. Addition or greatly increased efficiency HEDP in a synergistic manner. highest was obtained for molar ratios Ca/HEDP = 0.5 Zn/HEDP 3 . mechanism presence these additives proved to be different from that with alone related formation complex species...
Abstract Electron, neutron and X-ray diffraction patterns of liquid formamide have been measured at a temperature 25 °C. Analysis the data yields molecular structure average geometry hydrogen bond. The parameters obtained from experiments are in good agreement with those gas electron for free molecule. mean O…N O…H bond distances 2.9 Å 1.9 Å, respectively. Four H-bonds per molecule found on average. deviation linearity is estimated.
Abstract Electron-diffraction measurements for heavy and light water at 5°C are presented analysed in terms of atom-atom pair-correlation functions molecular correlation functions.
Abstract The study of the effectiveness several potential copper corrosion inhibitors in acidic media was studied. investigated thiazole derivative functional groups contain heterocyclic atoms such as nitrogen, sulfur, and oxygen.
