This work aims to optimize the recovery of methyl methacrylate (MMA) by depolymerization polymethyl (PMMA) dental resins fragments/residues. In order pilot experiments at technical scale, PMMA scraps were submitted thermogravimetric analysis (TG/DTG/DTA). The conducted 345, 405, and 420 °C, atmospheric pressure, using a scale reactor 143 L. liquid phase products obtained subjected fractional di...

stoichiometric tetragonal bal-xsrxtio3 (x = 0.23) nanopowders were prepared by stearic acid gel(sag) method using barium stearate, strontium stearate, tetrabutyl titanate as ba, sr, ti sourcesand stearic acid as complexing reagent. thermal analysis including differential thermogravimetric(dtg) and tg, fourier transform infrared spectrometry (ftir), x-ray diffraction (xrd) andtransmission electr...

Leather tanned with different agents was pyrolyzed in the presence of CoCl2 and MnCl2 catalysts. A bovine leather sample two inorganic tanning (chromium titanium salts) organic (glutaraldehyde methylacrylic resin) has been used this study. The samples were soaked solutions or known concentration. influence on decomposition temperature resultant pyrolysis compounds evaluated by using thermogravi...

-Iron doped Tin Selenide nanoparticles have been prepared by aqueous solution method in double distilled water at room temperature. All the chemicals used for this were of Analytical Reagent grade and of 99.999 % purity. Structural confirmation and particle size estimation of prepared SnSeFe0.5 Nanoparticles had been reported from Xray diffractogram obtained by CuKα radiation of wavelength 1.54...

This study aims to characterize the whole reaction process of (i) emulsion explosive matrix and sulfide ores, (ii) ammonium nitrate pyrite by thermodynamics analysis method. A series experiments were carried out at atmospheric pressure from 25 °C 350 four heating rates (3, 5, 10, 15 K/min) Coats–Redfern method was applied calculate apparent activation energy samples different rates. The results...
