摘要

摘要获得了四-3-羧基酞菁与铜的不溶于水的络合物。在 298.15 K 的不同 KOH 浓度（从 0.002 到 0.02 mol/L）的水溶液中溶解结晶四-3-羧基金属酞菁所产生的热效应是通过直接量热法测定的。测量是在热量计中进行的，热量计使用等温壳，自动记录温度，并在 T = (293.15-308.15) ± 0.01 K 和 P = 100.5 ± 0.7 kPa 时进行电气校准。计算了四-3-羧基酞菁络合物与铜在水溶液中解离产物的标准形成焓。使用 HEAT 计算机程序计算了逐步解离的热效应。

Thermochemistry of the Dissolution of Copper Tetra-3-carboxyphtalocyanine in Aqueous Solutions of KOH at 298.15 K

A complex of tetra-3-carboxyphthalocyanine with copper that is insoluble in water is obtained. Thermal effects from dissolving crystalline tetra-3-carboxymetalphthalocyanine in aqueous solutions of various KOH concentrations (from 0.002 to 0.02 mol/L) at 298.15 K are determined via direct calorimetry. Measurements are made in a calorimeter using an isothermal shell with automatic recording of the temperature and electrical calibration at T = (293.15–308.15) ± 0.01 K and P = 100.5 ± 0.7 kPa. Standard enthalpies of formation of the products of dissociation of the tetra-3-carboxyphthalocyanine complex with copper in aqueous solution are calculated. Thermal effects of stepwise dissociation are calculated using the HEAT computer program.
