Method for determining interaction of imidazoline derivative and corrosion inhibitor compounded components

The invention belongs to the technical field of compound determination and discloses a method for determining an interaction of imidazoline derivative and corrosion inhibitor compounded components which is characterized in that a synthesized imidazoline derivative is compounded with other types of corrosion inhibitors, chelating agents and synergists to master the interaction rules among the components of the corrosion inhibitor. In a compounding test, a corrosion inhibitor main agent, a corrosion inhibitor auxiliary agent, an active agent, a bactericide and a synergist are compounded. At present, about 15kt of the corrosion inhibitor is needed for domestic oilfield sewage treatment every year, and a total market amount is about 1.2 billion yuan. In addition to other industrial water treatment requirements, the total market demand of the corrosion inhibitor is 1.5-2.0 billion yuan. Oil and gas fields in China have stable market requirements for sewage treatment corrosion inhibitors which are good in corrosion
