Structure, Anticorrosion and Antibacterial Evaluation of (E)-3-(N-Oxide-methylimino)indolin-2-one

Аннотация

A nitrone, (E)-3-(N-oxide-methylimino)indolin-2-one, was synthesized and analyzed by X-ray single crystal analysis. The inhibition and the mechanism of action of the title compound on the corrosion of high protective Q235A steel in HCl solution were screened and discussed by weight loss and electrochemical measurements. The mechanism of action of (E)-3-(N-oxide-methylimino)indolin-2-one in HCl solution was screened for the corrosion of N80 steel in 1-methylindolin-2-one solution, and the inhibition mechanism was discussed. The results indicated that it can inhibit the corrosion with moderate inhibition efficiency in different conditions, and the mechanism of the corrosion inhibiting may be mainly contributed to the adsorption. It was screened for antibacterial activity against oilfield water-borne bacteria, and it showed good to moderate activity against sulfate reducing bacteria.
