✦ Synopsis

Abstract

On the basis of results so far available on inhibitors for water, sodium chloride and other salt solutions new results are reported which were obtained with respect to the inhibition in sodium persulfate solutions. The inhibitors studied in this context show increasing efficiency in the order nicotinic acid ‐ quinonline ‐ pyridine ‐ alpha‐picoline ‐ 2,4‐lutidine. The efficiency is primarily due to the nitrogen atom facilitating chemisorption of the particular compound to the metal surface. The efficiency may be interpreted in terms of the increased electron density of the heterocyclic system at the nitrogen atom.
