Thermal decomposition of some analgesic agents
(1996-06-01)
Thermogravimetry, derivative thermogravimetry (TG, DTG) and differential scanning calorimetry (DSC), were used to study the thermal behaviour of mefenamic acid, ibuprofen, acetaminophen, sodium diclofenac, phenylbutazone, ...
Thermal behavior of lignin and cellulose from waste composting process
(2013-01-01)
The lignin and cellulose were extracted from reference material (leaves and twigs) and food of compost at different times composting: zero (raw), 30, and 120 days. According to thermogravimetric analysis and its derivative ...
Refrigerator COP with thermal storage
(Pergamon-Elsevier B.V. Ltd, 2009-08-01)
Due to the extreme necessity to diversify renewable energy sources, the search for energy recycling methods through the utilization of thermal losses from equipment has become fundamental. Thus, these losses can be used ...
Synthesis, characterization and thermal behavior of solid state compounds of heavy trivalent lanthanide succinates
(2013-04-10)
Solid-state Ln-L compounds, where Ln stands for heavy trivalent lanthanides or yttrium(III) (Tb-Lu, Y) and L is succinate, have been synthesized. Simultaneous thermogravimetry and differential thermal analysis (TG-DTA), ...
Synthesis, thermal behavior and spectroscopic study of trivalentlanthanide and yttrium(III) α-hydroxyisobutyrates, in solid state
(2013-08-27)
Thermal and spectroscopic studies on solid trivalent lanthanides and yttrium(III) α-hydroxyisobutyrates, Ln(C4H7O 3)3·nH2O were investigated employing simultaneous thermogravimetry and differential thermal analysis (TG-DTA), ...
Thermal and crystalographic studies of mixture La2O3-SrO prepared via reaction in the solid state
(Kluwer Academic Publ, 1999-01-01)
The compound obtained via state solid reaction of the La2O3 and SrO oxides and expose the room atmosphere shows the crystallographic data of the compound reported as La2SrOx. However, thermogravimetric, differential thermal ...
THERMAL ANALYSES OF COORDINATION-COMPOUNDS .2. THERMAL-DECOMPOSITION OF PALLADIUM COMPLEXES WITH TRIPHENYLPHOSPHINE, TRIPHENYLARSINE AND TRIPHENYLSTIBINE
(Wiley-Blackwell, 1995-04-01)
The compounds [PdCl(2)L(2)] and [PdL(4)] (L=PPh(3), AsPh(3), SbPh(3)) were studied by thermogravimetric and differential thermal analyses in air. The residues of thermal decomposition consist of metallic palladium, except ...
Thermal behavior of some antihistamines
(2013-03-01)
Thermogravimetry (TG), differential scanning calorimetry (DSC), polarized light thermal microscopy (PLTM), as well as X-ray powder diffraction (XRD) and Fourier transformed infrared spectroscopy (FTIR) were used to study ...
Mechanochemical synthesis, characterization and thermal study of new cocrystals of ciprofloxacin with pyrazinoic acid and p-aminobenzoic acid
(2020-06-01)
Novel cocrystals of ciprofloxacin with pyrazinoic acid and p-aminobenzoic acid in the 1:1 stoichiometric ratio were obtained by the mechanochemical method, under conditions of liquid-assisted grinding (LAG/ethanol) and ...
Thermal analysis (TG–DSC, DSC–microscopy and EGA) and characterization of heavy trivalent lanthanides and yttrium isonicotinates
(2019-01-01)
The trivalent lanthanide isonicotinates were synthesized to obtain stoichiometry Lu(IN) 3 and Ln(IN) 3 ·2H 2 O (Ln = Tb to Lu, and Y; IN = isonicotinate). A deep study of the thermal behavior in oxidant (air) and inert (N ...
