| Abstract/Summary |
The crystal growth process of Zn(Thr)Ac2 • 2H2O from water and acetone was investigated using a Calvet microcalorimeter. The heat produced and the rate of heat production during the crystal growth process at 298.15 K, 301.15 K, 304.15 K, and 307.15 K were measured. On the basis of experimental and calculated results, the thermodynamic parameters (the apparent activation enthalpy, the activation entropy, and the activation Gibbs energy), the rate constant, and the kinetic parameters (the activation energy, the pre-exponential factor) during the crystal growth process were obtained. The results showed that the crystal process was in accord with the Burton—Cabrera— Frank dislocation theory.
