Abstract
The present study reveals the greener synthesis and corrosion inhibition study of
phenylamino cyclohex-2-enone (PAC) derivatives. Microwave assisted synthesis is
one of the safe and environmental friendly method to synthesize cyclohex-2-enone
compounds in presence of sodium bisulphate used as a catalyst and it is a highly
economical one. The cyclohex-2-enone compounds corrosion inhibitive effect proved
with the help of its weight loss. Synergetic process, electro chemical impedence
and potentiodynamic polarization studies was carried out for the target compounds.
The structures of synthesized cycloexenone compounds were elucidated with the help
of IR, 1H and 13C NMR. The type of adsorption isotherm was confirmed by using synergetic
process. The synergetic process was done by observing the correlation between halides
and inhibitor. The final results show that the compounds follow the Langmuir adsorption
isotherm.
