1. Product introduction
Imidazoline (CPI), a corrosion inhibitor for oil and gas fields, is prepared from amide compounds containing s and N synthesized by high temperature reaction with organic acid and organic amine as raw materials, supplemented by water, alcohol and oil solvents. Oil solubility of products supplemented with oil and alcohol as solvents. It is mainly used to protect oil and gas field pipes and equipment and reduce the corrosion of oil and gas field pipes and equipment due to various reasons.
