Abstract
Complexes are obtained of tetra-4-carboxyphthalocyanines with copper and zinc that are insoluble in water. Standard enthalpies of formation of the compounds are calculated according to additive groups based on group systematics with a Benson-type classification of fragments that considers the influence of the primary environment of atoms. Thermal effects of the dissolution of crystalline tetra-4-carboxymetallo-phthalocyanines in aqueous solutions at different concentrations of KOH (0.002 to 0.02 mol/L) at 298.15 K are determined via direct calorimetry. The standard enthalpies of formation are calculated for products of the dissociation of complexes of tetra-4-carboxyphthalocyanines with copper and zinc in aqueous solutions.
