Thermodynamic investigations of nitroxoline sublimation by simultaneous DSC-FTIR method and isothermal TG analysis

Characterization of the Sublimation and Vapor Pressure of 2-(2-Nitrovinyl) Furan (G-0) Using Thermogravimetric Analysis: Effects of Complexation with Cyclodextrins

“…The sublimation enthalpy and entropy from 35 to 60 °C obtained for G-0 were 86.5 kJ·mol −1 and 224.4 J·K −1 ·mol −1 , respectively. A similar value was obtained for the enthalpy of sublimation of the antibacterial urinary agent, nitroxoline (86.1 kJ·mol −1 ) [29].…”

DSC-FTIR microspectroscopy used to investigate the heat-induced intramolecular cyclic anhydride formation between Eudragit E and PVA copolymer

“…The thermal-responsive infrared (IR) spectra were simultaneously recorded over the course of the heating process. [13][14][15][16] RESULTS AND DISCUSSION Heat-induced ester condensation in the Eudragit E film For comparison, an Eudragit E film was examined using DSC-FTIR microspectroscopy. A three-dimensional plot of the transmission FTIR spectra of the Eudragit E film as a function of temperature in the IR range of 1900 to 800 cm À1 is shown in Figure 1a.…”

Thermodynamic Study of Grinding-Induced Loratadine Inclusion Complex Formation Using Thermal Analysis and Curve-Fitted FTIR Determination

“…The enthalpy of endothermic peak in the DSC curve was calculated. There was no oxidation or decomposition phenomenon observed in these determining conditions before the melting of LOR (Gao & Lin, 2010;Lin et al, 2006Lin et al, , 2010.…”

“…The infrared spectrum of each sample was analyzed with a Fourier transform infrared (FTIR) microspectroscopy (IRT-5000-16/FTIR-6200, Jasco Co., Tokyo, Japan) equipped with a mercury cadmium telluride (MCT) detector via a transmission technique (Gao & Lin, 2010;Lin et al, 2006Lin et al, , 2010. All the FTIR spectra were obtained at a 4 cm -1 resolution and at 100 scans.…”
