Metal corrosion inhibitor and preparation method thereof

The invention discloses a metal corrosion inhibitor and a preparation method thereof. The preparation method comprises the process steps of a natural gas storage CO2 liquid-phase corrosion inhibitor and a natural gas storage CO2 gas-phase corrosion inhibitor. The preparation method of the CO2 liquid-phase corrosion inhibitor for the natural gas storage comprises the following steps: S1, carrying out amidation and cyclization reaction on cis-octadecenoic acid-9-enoic acid and triethylenetetramine serving as main components, and dehydrating twice to form a five-membered heterocyclic imidazolineintermediate; s2, the imidazoline intermediate and benzyl chloride are subjected to quaternization, and oil solubility is converted into water-soluble imidazoline quaternary ammonium salt; and S3, reacting the imidazoline quaternary ammonium salt with ethyl sulfur nitrogen, and introducing an ethyl sulfur nitrogen polar group, so that the imidazoline quaternary ammonium salt has more active adsorption sites to obtain the natural gas storage CO2 liquid-phase corrosion inhibitor 2-ethylthio-amino-ethyl-benzyl-1-heptadecenyl-imidazoline quaternary ammonium salt. The corrosion inhibitor has gas-phase corrosion inhibition and liquid-phase corrosion inhibition functions at the same time, and the use concentration of the corrosion inhibitor can be reduced to a low degree on the premise that the function of the corrosion inhibitor is not affected.

Polyoxyethylene ether imidazoline sulfonate corrosion inhibitor and preparation method thereof

The invention discloses a polyoxyethylene ether imidazoline sulfonate corrosion inhibitor and a preparation method thereof. The structural formula of the corrosion inhibitor is shown in the specification, R represents the saturated alkyl group with the carbon chain number ranging from C11 to C17, the monoene group or the diene group, and n is an integer ranging from 5 to 15. According to the method, a long-carbon-chain imidazoline intermediate is synthesized from raw materials including long-carbon-chain carboxylic acid and diethylenetriamine firstly, then the long-carbon-chain imidazoline intermediate and ethylene oxide are subjected to the addition reaction under the alkaline condition, polyoxyethylene ether imidazoline is produced, the polyoxyethylene ether imidazoline and 3-chloro-2-sodium hydroxypropanesulfonate are subjected to the quaterisation reaction finally, and the corrosion inhibitor is prepared. Active groups, namely, -OH and -SO3 are introduced in the structure of thecorrosion inhibitor, so that the corrosion inhibitor has the good solubleness in water, the adsorption activity on the metal surface is greatly enhanced, and the excellent corrosion inhibition performance is shown; and the corrosion inhibitor is good in biological degradability, low in toxicity and environment-friendly. The corrosion inhibitor can be applied to oil-field-produced aqueous media containing CO2 and H2S and can be applied to high-temperature and high-pressure media of CO2 displacement systems for slowing down corrosion of fluids to carbon steel.

Some imidazoline derivatives as corrosion inhibitors

In this study, cationic surfactants having different alkyl chain lengths were prepared by amidation of lauric, myristic, palmitic, stearic, oleic acids with diethylene triamine. The products were quaternized using chlo-roacetic acid. The chemical structure of the prepared compounds was elucidated using different spectroscopic techniques. The critical micelle concentration (CMC) and the free energy of the micellization and adsorption of these compounds were determined by surface tension and conductivity measurements. The products were evaluated as surface-active agents as well as corrosion inhibitors for steel alloy in 1 M hydrochloric and sulfuric acid, the results indicate that these materials have a high efficiency as corrosion inhibitors and as surface active agents. These results were correlated with the chemical structure of the prepared compounds. AOCS 2009.
