Study of the thermal behavior in oxidative and pyrolysis conditions of some transition metals complexes with Lornoxicam as ligand using the techniques: TG-DSC, DSC, HSM and EGA (TG-FTIR and HSM-MS)

Abstract

Lornoxicam metal complexes [M(Lor)2(OH2)2]•nH2O, where M represents the bivalent transition metals (Mn(II) to Zn(II)), Lor is Lornoxicam ligand and n = 2.0 or 2.5 were synthesized. The compounds were characterized by elemental analysis (EA), powder X-ray diffraction (PXRD), infrared spectroscopy (FTIR), simultaneous thermogravimetry and differential scanning calorimetry (TG-DSC) under oxidizing and pyrolysis conditions, differential scanning calorimetry (DSC), hot-stage microscopy (HSM) and evolved gas analysis (EGA) by coupled hot-stage microscopy (HSM-MS) and Fourier transform infrared (TG−FTIR). Regardless of the atmosphere, the thermal stability and thermal behavior up to the first two mass loss steps of the anhydrous compound were similar, only differing significantly in the last steps.

Efficient preadsorption–degradation of PFOA in water by a NaClO-assisted electrocoagulation technique using an Fe/Ni foam electrode

“…However, a larger mass loss of 29.4% is observed after PFOA adsorption, which is attributed to the thermal decomposition of PFOA. 36 This confirms the formation of Fe-PFOA complexes during the EC process. The total mass loss of Fe flocs generated in the EC-NaClO process was reduced by 10% compared with the EC process alone, which demonstrated the successful degradation of PFOA in the "preadsorption-degradation" reaction system.…”

Exploring pyrolysis characteristics of bituminous coal: a combined modelling and experimental investigation with TG-IR

“…In this current investigation, the effect of operating conditions on the pyrolysis behaviour of coal is characterised using the TG-IR technique (Song et al, 2017;Zangaro et al, 2019). Besides, kinetic modelling was carried out for the kinetic and diffusion regime of pyrolysis, known as two-stage kinetic modelling (Song et al, 2017).…”

Kinetics of Dehydroxylation and Decarburization of Coal Series Kaolinite during Calcination: A Novel Kinetic Method Based on Gaseous Products

“…Nonetheless, the gaseous products released by the reactions in CSK are different, which can be distinguished by detecting product release. With the development of thermal analysis technology, Thermogravimetric analysis-Fourier Transform Infrared Spectrometer-Mass Spectrometer (TG-FTIR-MS) technology has been widely used to detect gaseous products [ 18 , 19 , 20 ]. In TG-FTIR-MS, the gaseous products can be detected and identified by the FTIR detector.…”
