摘要

合成了钴-四羧基酞菁配合物。用直接量热法测定了结晶四羧基金属酞菁钴在不同浓度（0.002 ~ 0.02 mol/L）的KOH水溶液中298.15 K溶解的热效应。该化合物的标准生成焓是使用加性基团计算的，基于基团系统学，采用本森类型的碎片分类，考虑了原子主要环境的影响。标准生成焓计算了四-4-羧基酞菁-钴络合物在水溶液中解离的产物。

Thermochemistry of Dissolution of Cobalt Tetra-4-carboxymetallophthalocyanine in Aqueous Solutions of Potassium Hydroxide at 298.15 K

Cobalt–tetra-4-carboxyphthalocyanine complexes are synthesized. Direct calorimetry is used to determine heat effects of the dissolution of crystalline cobalt tetra-4-carboxymetallophthalocyanine in KOH aqueous solutions of various concentrations (0.002–0.02 mol/L) at 298.15 K. The standard enthalpies of formation of the compound are calculated using additive groups, based on group systematics with a Benson-type classification of fragments that considers the effect of the primary environment of atoms. Standard enthalpies of formation are calculated for products of the dissociation of tetra-4-carboxyphthalocyanine–cobalt complexes in an aqueous solution.
