Исследование пропаргиловых эфиров аминометилированных алкенилфенолов в качестве ингибиторов коррозии черных металлов
Keywords: inhibitors, metal corrosion, acid corrosion, degree of surface filling, adsorption energy, chemisorption.
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 (DGads) were calculated, confirming the mechanism for protecting the steel surface from acid corrosion by forming chemisorbed adsorption layers on it.
