Such a protic acid as formic acid is possible to react with anhydrous methanol. Effect of the formic acid reaction with methanol on the corrosion rate of iron in an anhydrous methanol solution of 0.1M NaClO4 was investigated by cyclic voltammetry and impedance measurement. The corrosion rate was lowered as the concentration of formic acid decreased with an increase in the immersion time. The fomation of methyl formate and water by the reaction complicates the process of iron corrosion in the methanol solution.
