2), again by temperature 180-220 DEG C is risen to, stirring, react and obtain imidazolinium compounds in 2-6 hour；
3), in step 2) imidazolinium compounds that obtains drips quaternizing agent, control temperature at 100-140 DEG C, drip
Add complete follow-up continuous stirring 3-6 hour prepared novel corrosion inhibitor of reaction.
Having the beneficial effects that relative to prior art: by first synthesizing imidazolinium compounds, then to product
The method carrying out quaternization prepares novel corrosion inhibitor, and this corrosion inhibiter is respectively provided with prominent for carbon steel, pyrite, aluminum and alloy thereof etc.
Corrosion inhibition, hydrogen sulfide and carbon dioxide are had good inhibiting effect, there is stronger amphipathic property, inhibition simultaneously
Rate is high, use the advantages such as simple；This preparation method is simple, improves corrosion inhibiter corrosion inhibition rate, and this corrosion inhibiter environmental sound,
Wide adaptability, is environmentally friendly novel corrosion inhibitor.
