<p>An anticorrosive for vapor/condensed water systems, which comprises at least one aminodiol represented by the following general formula: <CHEM> (in which R1, R2 and R3 each represents -H, -CH3, -C2H5 or -CH3; and n represents an integer of 0 to 2) and the process for inhibiting the corrosion of vapor/condensed water systems, which comprises at least one aminodiol as mentioned above to a boiler feed water at the concentration of 0.1 to 500 mg/l. The aminodiol, when added to feed water, migrates into condensed water in large quantities and inhibits the corrosion of piping systems and boilers in highly effective manner.</p> |
