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. The products supplemented with water and alcohol are water-soluble. 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.
