Description

Complex formation of mesoporphyrin, pyroporphyrin and rhodoporphyrin with copper(2), zinc(2) and cadmium(2) nitrates in acetone, 1.4-dioxane and ethyl acetate at a temperature of 295-318 K was studied. The data obtained were used for estimating constant rates, activation energy and entropy of reaction. By transfer from acetone to dioxane and ethylacetate complex formation rate was decreasing by one-two orders independently of metal cation nature. Solventleveling effect on complex formation is attributed to steric properties of solvate shell of salts
