Corrosion Inhibition of Mild Steel in Nitric Acid Media by some Schiff Bases Derived from Anisalidine

Abstract

Corrosion inhibition performance of mild steel in nitric acid solution containing different concentration of anisalidine derivative Schiff bases viz. N-(4-nitro phenyl) p-anisalidine (SB1), N-(4-chloro phenyl) p-anisalidine (SB2), N-(4-phenyl) p-anisalidine (SB3), N-(4-methoxy phenyl) p-anisalidine (SB4), N-(4-hydroxy phenyl) p-anisalidine (SB5) has been investigated using mass loss, thermometric and potentiostate polarization technique. Inhibition effi ciencies of Schiff bases have been evaluated at different acid strength. The inhibition effi ciency was found larger than their parent amines. Inhibition effi ciencies of synthesized Schiff bases increase with inhibitor concentration. Inhibition effi ciency increases up to 98.32% with ansalidine derivative Schiff base.

Experimental study of the inhibitory effect of ceftriaxone sodium and sodium nitrate on corrosion of carbon steel in various acidic media

“…The performance of synthesized Schiff bases enhance with inhibitor concentration. The efficiency of Inhibition improves up to 98.32% with ansalidine derivative Schiff base [18]. Kalla et al (2016) studied the performance of ethyl acetate extract (EAE) and butanolic extract (BE) of Thapsia villosa as corrosion inhibitors of carbon steel metal in 1 M H2SO4 using different methods as follow: electrochemical impedance spectroscopy (EIS) method, potentiodynamic polarization, and weight loss methods.…”

Green inhibitors for steel corrosion in acidic environment: state of art

“…These are known to contain superior anti-glycating agents, which because of containing electronegative oxygen, nitrogen, and aromatic rings acting as active adsorption centers on the metal surface thereby rendering them effective green inhibitors [25]. This class of inhibitors offers the benefit of easy production from inexpensive rendering them to be competitive alternates for toxic traditional inhibitors [26,27]…”

Chemical modification at the surface and corrosion inhibition response of two semicarbazones on carbon steel in HCl medium

“…Molecules equipped with active corrosion inhibition sites such as hetero atoms like O, S, N, aromatic rings and Schiff bases are found to act as efficient corrosion inhibitors in aggressive media [1][2][3][4][5][6][7]. A few semicarbazones and hydrazones exhibited good corrosion protection ability due to the presence of C=N group [11,16].…”
