| titleOfInvention | A kind of triazine ring polyquaternary ammonium salt antioxidant corrosion inhibitor and its preparation method and application |
| abstract | The invention discloses a triazine ring polyquaternary ammonium salt anti-oxidation corrosion inhibitor and its preparation method and application. The preparation method of the anti-oxygen corrosion inhibitor comprises the following steps: dissolving cyanuric chloride in an organic solvent, In an ice-water bath, slowly drop the solution of the compound shown in Formula I into the solution containing cyanuric chloride, stir for 2-3h, then heat up to 30-40°C for 4-6h, then heat up to 70-80°C for reaction 5‑12h; after cooling to room temperature, vacuum distillation, washing, filtering, and drying were obtained. The corrosion inhibitor has good corrosion inhibition performance at high temperature. When the corrosion inhibitor is used as an anti-oxygen corrosion inhibitor for gas injection wells, it has good solubility in high-salinity formation water, and it is resistant to oxygen corrosion of carbon steel in gas injection wells. have obvious inhibitory effect. |
