Abstract
The corrosion inhibition potentials of some derivatives of 2-((1H-indol-2-yl)thio)-6-amino-4-phenylpyridine-3,5-dicarbonitrile (TAPD) namely 2-(1H-indol-2-ylthio)-6-amino-4-(4-nitrophenyl)pyridine-3,5-dicarbonitrile (TAPD-I), 2-((1H-indol-2-yl)thio)-6-amino-4-phenylpyridine-3,5-dicarbonitrile (TAPD-II), and 2-(1H-indol-2-ylthio)-6-amino-4-(4-hydroxyphenyl)pyridine-3,5-dicarbonitrile (TAPD-III) on mild steel in 1 M HCl solution have been investigated using experimental and computational methods.
