Abstract

Some 3-methyl-1-butyne derivatives are tested as inhibitors of Armco iron corrosion in 1 N HCl at 70 °C. The substitution of the acetylenic H atom with halogen atoms improves their inhibitive performances and their polymeric surface film acts through a blocking effect of the active metal surface. 1-octyne-3-ol is highly efficient and its polymeric surface film acts as a physical barrier to H+ discharge and markedly hinders also the anodic iron oxidation reaction.
