Abstract

Aminoalkylphosphonic acids exhibit a high anticorrosion effect toward carbon and low-alloy steels [1–2]. A large number of compounds of this type were synthesized by aminoalkylation of phosphonic acid derivatives [3]. this way contain a one-carbon bridge connecting the nitrogen and phosphorus atoms, whereas extension of that bridge should lead to increased size of the dipole and enhanced adsorbance, which should improve protective properties ...
