In the present paper, the physicochemical incompatibility of doxepin with dextrose was evaluated in solid-state mixtures. The compatibility was evaluated using different physicochemical methods such as differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy and mass spectrometry. Non-isothermally stressed physical mixtures were used to study the solidstate kinetic parameters. Different thermal models such as Friedman, Flynn-Wall-Ozawa and Kissinger-AkahiraSunose were used for the characterization of the drugexcipient mixtures. Overall, the incompatibility of doxepin as a tertiary amine with dextrose as a reducing carbohydrate was successfully assessed. DSC-based kinetic analysis is a simple and fast method in evaluation of different drug-excipient mixtures incompatibility. Finally, it can be recommended to exclude dextrose from doxepin pharmaceutical formulations and also to apply the easy and versatile DSC method in kinetic study of drug-excipient incompatibility.

The hydrolysis of copper (II) chloride is the water splitting process in the copper-chlorine thermochemical hydrogen production cycle. In this paper, a simultaneous differential scanning calorimetry and thermogravimetric analysis (DSC / TGA) technique is used to determine the transitional temperature and kinetics of the thermal decomposition of CuCl2. Thermodynamic analysis is performed on the decomposition reaction for a comparison with the thermogravimetric analysis results. The CuCl2 decomposition temperature obtained from thermogravimetric experiments is found to be higher than that predicted from the thermodynamic analysis. This broadens the available operating temperature range of the CuCl2 hydrolysis step for the Cu-Cl cycle. It is also found that the decomposition product CuCl may completely evaporate if the temperature is higher than its melting point, so the CuCl2 hydrolysis reaction should be operated below the melting point of CuCl (430 o C) to avoid the undesirable CuCl and Cl2 by-products. A preliminary correlation was proposed in this paper for the decomposition kinetics in terms of the extent of converting CuCl2 to CuCl and Cl2.
