Dependence of the Protective Properties of Mixtures Based on Several Reaction Series on the Number and Concentrations of the Components
Mixtures based on azomethine, imidazobenzoimidazole, and pyrimidobenzoimidazole derivatives were tested as inhibitors of iron corrosion in 1 M H^sub 2^SO^sub 4^ in the presence of 0.25 mol/l NaCl. The number and concentrations of their components were varied with the aim of studying their influence...

| description | Mixtures based on azomethine, imidazobenzoimidazole, and pyrimidobenzoimidazole derivatives were tested as inhibitors of iron corrosion in 1 M H^sub 2^SO^sub 4^ in the presence of 0.25 mol/l NaCl. The number and concentrations of their components were varied with the aim of studying their influence on the protection effects of the mixtures. The resulting experimental dependences, of the protective effectiveness on the number and concentration of the components, as well as the polar properties of substituents in their molecules, can be interpreted in terms of the linear Gibbs energy relation (LGER). This conclusion is valid over a wide range of medium temperatures (20-60°C), provided the volume concentrations of compounds in each reaction series are kept constant.[PUBLICATION ABSTRACT] |
