Abstract: Five organic volatile corrosion inhibitors (VCIs) were synthesized using 2-Dec-9-enyl- 2-imidazoline with various acids such as maleic acid, orthophosphoric acid , nitrobenzoic acid , phthalic acid and cinnamic acid and evaluated as corrosion inhibitors of mild steel, brass and copper by weight loss method. Eschke test method, sodium chloride inoculation test method and sulfur dioxide (SO2) test method were also carried out to investigate the corrosion inhibiting effect of the compounds. All the investigated VCIs exhibited good inhibition efficiency (IE) for all the metals. Cinnamate salt showed best result among all the studied compounds for all the metals.
