Abstract

The kinetics of the complex formation reactions of tetraphenylporphine with zinc and cadmium acetates in mixed solvents containing alcohols and inert diluents was studied by electronic absorption spectroscopy. The dependences of the rate constant on the binary solvent composition have an extreme character, which is universal in the temperature range 298–313 K for different salts, alcohols, and weakly solvating diluents. The electric conductivity of zinc acetate solutions was measured in a wide range of compositions of alcohol-chloroform binary solvents. The electric conductivity increased with an increase in the content of alcohols.
