ANTICORROSIVE ACTIVITY OF SCHIFFS BASES SUBSTITUTED IN ANILINE RINGS

A correlation is shown to exist between the cathodic polarizability of CT3 steel in 0.05 N KCl solution at 22 degrees C under the films that contain inhibitors based on thirty-one substituted derivatives of ben zylidene-aniline, on the one hand, and the basicity of inhibitors and the electron donor and acceptor properties of the substituents, on the other hand. In the electronic effect of substituents on the reaction center of inhibitors, the contributions of the inductive effect and th e mesomeric conjugation are estimated.
