The protection of metals against corrosion by means of volatile compounds is the most progressive method of fighting metallic corrosion. These inhibitors are used to protect metallic articles and equipment during storage and transportation. In view of this we have synthesized six organic volatile corrosion inhibitors (VCIs) using Lauric hydrazide with various acids such as cinnamic acid, succinic acid, nitrobenzoic acid, phthalic acid and maleic acid and evaluated their inhibiting action on corrosion of mild steel, copper, brass, zinc and aluminium by weight loss and potentiodynamic polarization methods. All the investigated VCIs exhibited good inhibition efficiency for all the metals.
