The energy of activation for the corrosion of aluminium (composition : Si 0.11, Fe 0.20, Ti 0.03% and Al remainder) in aqueous sodium hydroxide (0.1-1.0M) was 9.66 Kcal/mole and for the inhibited by 02wt% catechol w as 7.78 Kcal/mole in the temperature range 30-70℃.
It can be said that the corrosion reaction was relatively temperature-insensitive by catechol.
