Studies on Amine-type Corrosion Inhibitors (8th Report)

Experimental and theoretical studies of Schiff bases as corrosion inhibitors

BACKGROUND Relatively inexpensive, stable Schiff bases, namely 3-((4-hydroxybenzylidene)amino)-2-methylquinazolin-4(3H)-one (BZ3) and 3-((4-(dimethylamino)benzylidene)amino)-2-methylquinazolin-4(3H)-one (BZ4), were employed as highly efficient inhibitors of mild steel corrosion by corrosive acid. FINDINGS The inhibition efficiencies were estimated based on weight loss method. Moreover, scanni...

Report on the 8th IAMC Annual Meeting

Controlling Corrosion in Amine Treating Plants

The causes and the prevention of carbon steel corrosion in amine systems are reviewed. The corrosive agents are acid gases, oxygen, heat stable salts, amine degradation products, and, in refineries, gas contaminants such as ammonia and hydrogen cyanide. Corrosion mechanisms are provided for carbon steel exposed to amine solutions and for amine regenerator overhead systems containing aqueous con...

Amine oxidase inhibitors.

W E HAVE HAD a keen interest in the monoamine oxidase inhibitors (MAOinhibitors) from the time that Cesarman' first reported their benefits in the prophylaxis of angina pectoris. Together with two of my associates, Dr. Robert W. Oblath and Dr. Willard J. Zinn, I have used four of the available MAO-inhibitors-iproniazid, isocarboxazid, beta-phenylisopropylhydrazine, and pivalylbenzhydrazine-in t...
