“…A mechanical cooling system was used for the experimental measurement. The temperature scale of the instrument was initially calibrated in the standard DSC mode, using the extrapolated onset temperatures of the melting of indium (429.75 K), as described in our previous articles [27][28][29][30][31][32]. The energy scale was calibrated with the heat of fusion of indium (28.45 J g -1 ).…”

Two metal-organic frameworks, Ca(2,6-NDC) (DMF) (1) and Mn 3 (2,6-NDC) 3 (DMF) 4 (2) (where 2,6-NDC = 2,6-naphthalene dicarboxylate and DMF = N,N 0 -dimethylformamide) have been solvothermally synthesized under optimized conditions and characterized by X-ray powder diffraction, elemental analysis, FT-IR spectroscopy, and TG analysis. The thermal decomposition characteristics were investigated under air atmosphere from 300 to 1,170 K (for 1) and from 300 to 971 K (for 2). The molar heat capacities were measured from 198 to 548 K (for 1) and from 198 to 448 K (for 2) by temperature modulated differential scanning calorimetry (TMDSC) for the first time. The fundamental thermodynamic parameters such as entropy and enthalpy variations with temperature were calculated based on the experimentally determined molar heat capacities.

“…[7] It is well known that Friedman's method is very sensitive to experimental noise and tends to become numerically unstable because of employing instantaneous rate values. [28] On the other hand, in the OFW method the equation is derived assuming constant activation energy, introducing a systematic error in the estimation of E when the activation energy varies with conversion. [29] Even though there was a slight difference in the E values of PTBT copolymers derived from the OFW and Friedman's methods, both methods revealed the same trend of activation energies for whole conversion, i.e.…”

The thermal stability and thermal decomposition kinetics of poly(trimethylene-cobutylene terephthalate) (PTBT) copolymers in nitrogen were studied by means of thermogravimetry. The PTBT copolymers had good thermal stability in nitrogen and the introduction of copolymer component had a slight influence on the thermal stability of copolymers. The mass loss of PTBT copolymer was accomplished in one main mass loss stage and one small weight loss in the early stage of decomposition. The PTBT copolymers started to decompose at ≈350.0 • C and completed decomposition at ≈440.0 • C with the heating rate of 5 • C/min. The characteristic degradation temperatures of PTBT copolymers shifted toward higher temperatures with increasing heating rates and poly(trimethylene terephthalate (PTT) content. Furthermore, various degradation methods, including the Ozawa-Flynn-Wall method, Friedman's method, and Kissinger's method, were used to determine the activation energies of copolymers. The three methods were applicable to the kinetic description of thermal degradation of PTBT copolymers. The thermal activation energies obtained by three methods were in satisfactory conformity. The thermal degradation kinetics of copolymers could be interpreted in terms of multi-step degradation mechanisms. It was shown that the thermal stability of PTBT copolymers increased with increase in PTT content. Copolymers with higher PTT content showed higher degradation temperature and thermal activation energy. A general activation energy range of 180-200 kJ/mol was suggested for the processing and use of PTBT copolymer fibers.

A three-dimensional lithium-based metalorganic framework Li 2 (2,6-NDC) (2,6-NDC = 2,6-naphthalene dicarboxylate) has been synthesized solvothermally and characterized by X-ray powder diffraction, elemental analysis, FT-IR spectroscopy, thermogravimetry and mass spectrometer analysis (TG-MS). The framework has exceptional stability and is stable to 863 K. The thermal decomposition characteristic of this compound was investigated through the TG-MS from 293 to 1250 K. The molar heat capacity of the compound was measured by temperature modulated differential scanning calorimetry (TMDSC) over the temperature range from 195 to 670 K for the first time. The thermodynamic parameters such as entropy and enthalpy versus 298.15 K based on the above molar heat capacity were calculated.
