Thermal Decomposition of Pentacene Oxyradicals

The Journal of Physical Chemistry A, 2011
The energetics and kinetics of the thermal decomposition of pentacene oxyradicals were studied using a combination of ab initio electronic structure theory and energy-transfer master equation modeling. The rate coefficients of pentacene oxyradical decomposition were computed for the range of 1500-2500 K and 0.01-10 atm and found to be both temperature ...

THE THERMAL DECOMPOSITION OF CARBOHYDRATES

Canadian Journal of Research, 1948
The thermal decompositions of cellobiose, maltose, dextrose, and potato starch have been studied over a temperature range, by following the production of volatile products. Carbon dioxide, carbon monoxide, and water with small quantities of acids, aldehydes, and volatile solids were produced in all cases.

Thermal decomposition of dicyclopentadienylarylvanadium compounds

Journal of Organometallic Chemistry, 1977
The thermolysis of compounds of the type Cp2VR (R = aryl) in the solid state has been studied. A distinct increase in thermal stability is observed upon substitution of the ortho-position of the aryl group. Thermal decomposition occurs with formation of RH, Cp2V, a vanadocene homologue with the group R substituted in one of the Cp rings and, probably ...

Thermal Decomposition of Potassium Perchlorate

Nature, 1950
PERCHLORIC acid is often determined as potassium chloride by repeated ignition of potassium perchlorate, mixed with excess ammonium chloride and in presence of platinum as catalyst. It is currently assumed that the reducing agent is the ammonia, though K. A. Hofmann and W. Linnmann1 have shown that gaseous ammonia does not reduce perchlorate below 430°

Thermal decomposition products of butyraldehyde

The Journal of Chemical Physics, 2013
The thermal decomposition of gas-phase butyraldehyde, CH3CH2CH2CHO, was studied in the 1300–1600 K range with a hyperthermal nozzle. Products were identified via matrix-isolation Fourier transform infrared spectroscopy and photoionization mass spectrometry in separate experiments.

Thermal decomposition of developing enamel

Calcified Tissue International, 1990
The decomposition of forming, maturing, and mature enamel was studied between room temperature and 1,000 degrees C by powder X-ray diffraction and infrared absorption methods. In mature dental enamel, carbonate decomposition proceeds relatively fast until 500 degrees C and at a slower rate beyond it.

The thermal decomposition of methyl chloroformate

Australian Journal of Chemistry, 1976
In the presence of inhibitors, methyl chloroformate decomposes at 425- 480° to methyl chloride and carbon dioxide in a homogeneous molecular reaction.

CHARACTERIZATION AND THERMAL DECOMPOSITION OF CERUSSITE

Metallurgical & Materials Engineering Congress of South-East Europe
Due to its physical characteristics, lead is one of the most important non-ferrous metals in the world. Metallic lead and its alloys have significant applications in the mechanical industry, radioactive protection, battery industry, as well as in many other industries. In most cases, lead is found in nature in the form of sulphide minerals (galena), as

Thermal Growth and Decomposition of Methylnaphthalenes

Environmental Science & Technology, 2005
Diesel particulate matter (DPM) has been recognized as carcinogenic due to its respirable sizes and toxic compositions. It is essential to understand its formation mechanisms to effectively reduce DPM emissions. Studies have indicated that resonance stabilize radicals can result in more soot and PAC (polycyclic aromatic compounds) formation in ...

Thermal decomposition of β-FeOOH

Materials Letters, 2004
beta-FeOOH particles were prepared by a forced hydrolysis of the 0.1 M FeCl3 + 5(.)10(-3) M HCl solution, whereas sulfated beta-FeOOH particles were prepared by forced hydrolysis of the 0.1 M FeCl3 solution containing 5.10(-3) M quinine hydrogen sulfate (QHS).
