kinetics and mechanism of the thermal decomposition of tetrammine copper(II) sulphatemonohydrate have been studied using non-isothermal thermogravimetry. Kinetic parameters were calculated for each step in the decomposition reaction from the TG curve using four integral methods, three “exact” and one “approximate”. The rate-controlling process for all the four stages of decomposition is random nucleation
摘要 使用非等温热重法研究了四胺硫酸铜(II)一水合物的热分解动力学和机理。使用四种积分方法(三种“精确”和一种“近似”)从 TG 曲线计算分解反应中每个步骤的动力学参数。所有四个分解阶段的速率控制过程是随机成核,每个粒子上形成一个核(Mampel 方程)。分解阶段已从 X 射线衍射和独立热解中确定。

measurements of mixtures of cupric nitrate2 or chloride3, with ammonium hydroxidesolutions, of various compositions. The conductometric curves gave breaks corresponding to three, four, five and six molecules of ammonia for one molecule of the copper salt, thus affording the evidence for the existence of tri-, tetra-, penta- and hexa-ammino cupric compounds. In the case of cupric ammino sulphates, however
