A potential model for the prediction of metal corrosion inhibition using relevant pure and mixed surfactants in salt solution was developed and validated. This model is based on the combination of Langmuir adsorption (LA) and a newly-developed critical micelle concentration (cmc) prediction model for various pure and mixed surfactants. The collected data from benzalkonium chloride (BAC) surfactants was used for model illustration and derivation. The effects of surfactant concentration, adsorption, aggregation, and solution temperature on steel corrosion inhibition were investigated. The adsorption mechanism is discussed based on temperature, concentration, potential of zero charge, and d. functional theory (DFT) calculation In the experiment, the researchers used many compounds, for example, 1-Dodecylpyridin-1-ium bromide (cas: 104-73-4Quality Control of 1-Dodecylpyridin-1-ium bromide).
1-Dodecylpyridin-1-ium bromide (cas: 104-73-4) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized. The nitrogen is involved in the π-bonding aromatic system using its unhybridized p orbital. The lone pair is in an sp2 orbital, projecting outward from the ring in the same plane as the σ bonds. Halopyridines are particularly attractive synthetic building blocks in a variety of cross-coupling methods, including the Suzuki-Miyaura cross-coupling reaction.Quality Control of 1-Dodecylpyridin-1-ium bromide
