摘要：
The effect of benzaldehyde and its ortho and para -OH and -OCH3 derivatives on the rate of dissolution of Brass alloy in nitric acid was investigated using thermometric technique. The results were treated by two different methods. It has been found that all compounds act as inhibitors and their effect increases with increasing concentration. The o-OH and o-OCH3 derivatives have the highest inhibition effect.
