Synthesis and properties of corrosion inhibitor and bactericide 1- acylamino -1- alkyl phosphonic acid on oil-field flooding

In this paper Mannich reaction between higher amide ketone and phosphorus(III) chloride was used to synthesize two kinds of amide alkyl phosphate compounds and weight - loss method permanent potential scan method was used to test their corrosion inhibition in the environment of oil field injection water. Their biological activity has also been investigated. They have very strong sterilization performance. Also the paper has analysed their adsorption form and corrosion inhibition mechanism sample surface.
