“…Although the decomposition temperature found in our setup corresponds reasonably well to the temperatures reported by Ismail 8 and Jasim et al, 9 the reaction products differ from those measured by Ismail. Ismail reports propyne and acetone as gaseous reaction products while acetylacetone, acetaldehyde, and CO are detected in our setup and are also reported by Jasim et al Acetylacetone, acetone, and CO are reported by Turgambaeva 6 to be the main gaseous reaction products of the metal acetylacetonates of Mg, Hf, Cu, Al, and Sc.…”

“…IR-spectrometry and X-ray diffraction have been used to analyze the reaction products. Jasim et al 9 also used TGA and DTA to investigate the thermolysis of Fe(acac) 3 , but employed a chromatographic analyzer to identify the gaseous reaction products. The thermolysis of TBDS has been investigated by Bock et al 10 using photoelectron spectrometry supported by thermodynamic calculations.…”

Pyrite, FeS 2 , thin films have been prepared by metallorganic chemical vapor deposition using tert-butyl disulfide (TBDS) and iron(III) acetylacetonate [Fe(acac) 3 ] as the precursors and H 2 as co-reactant. The reaction mechanism is studied with in situ mass spectrometry. The thermal decomposition of TBDS and Fe(acac) 3 has been investigated, as well as the synthesis of FeS 2 . A complicated gas-phase reaction chain occurs in the deposition reaction. In the first 1-2 cm of the deposition zone, thick rough films are formed, but further downstream in the reactor a smooth FeS 2 film is deposited. This remarkable change in morphology is accounted for in the proposed reaction mechanism.

“…The gaseous products evolved from the [Fe(acac) 3 ]/TEG reactant mixture were followed by mass spectrometry and found to be mainly acetaldehyde (C 2 H 4 O), CO 2 , and CO, in accordance with results reported by Jasim and Hamid and Reijnen et al for the thermal decomposition of several metal acetylacetonates. The evolution of the signals corresponding to m / z = 44, (C 2 H 4 O + CO 2 ), and m / z = 28 (CO) is shown in Figure b.…”

The nucleation and growth of water dispersible iron-oxide nanoparticles synthesized by high temperature decomposition of iron(III) acetylacetonate in the presence of different solvents has been studied. A battery of techniques was used to characterize the products obtained under different conditions and to elucidate the synthesis mechanism. Results show that the synthesis of iron-oxide nanoparticles in triethylene glycol (TEG) proceeds through a multistep process whose first stage is likely to be the formation of an intermediate TEG-iron-complex that evolves into a low-crystallinity iron-oxide-organic precursor during aging at 180 °C. Raising the temperature above 240 °C caused the thermal decomposition of the precursor and the sudden nucleation of small iron-oxide nanocrystals. Keeping the reactant mixture at 280 °C led to the growth of iron-oxide nanocrystals, as did increasing the time at reflux temperature, the amount of initial iron precursor or the use high boiling point solvents. The particle size could be reproducibly controlled between 1.5 and 13 nm, with a relatively narrow size distribution. Larger particles could also be obtained using a solvothermal method in an autoclave reactor.
