Abstract: Three volatile corrosion inhibitors (VCIs) namely, benzoic hydrazide benzoate (BHB), benzoic hydrazide salicylate (BHS), and benzoic hydrazide nitrobenzoate (BHN), were synthesized and evaluated as corrosion inhibitors of mild steel, brass and copper by weight loss method. Eschke test method, sodium chloride inoculation test method and sulphur 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. Benzoate salt showed best result among all the studied compounds for all the metals.
