Study of propargyl ethers of aminomethylated alkenylphenols as corrosion inhibitors of ferrous metals

Abstract

. The article presents the results of studies on the evaluation of the adsorption properties of three aromatic compounds containing simultaneously several active centers in the structures - fragments with double and triple bonds and an aminomethyl group: 1-propenyl-2-propargyloxy-3-diethylaminomethylbenzene (I), 1-allyl- 2-propargyloxy-3-diethylaminomethylbenzene (II) and 1-allyl-2-propargyloxy-3-morphoaminomethylbenzene (III). Based on the data of gravimetric studies, the adsorption-desorption constants (Kads), as well as the adsorption energy (Gads) were calculated, confirming the mechanism for protecting the steel surface from acid corrosion by forming chemisorbed adsorption layers on it.
