Thermal Growth and Decomposition of Methylnaphthalenes
Environmental Science & Technology, 2005Diesel 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, 2004beta-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).

CHARACTERIZATION AND THERMAL DECOMPOSITION OF CERUSSITE
Metallurgical & Materials Engineering Congress of South-East EuropeDue 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 decomposition processes in polycarbonates
Polymer Degradation and Stability, 1989The thermal decomposition mechanisms of some polycarbonates have been investigated by direct pyrolysis mass spectrometry. The results indicate that aliphatic polycarbonates decompose by intramolecular exchange processes which produce cyclic compounds as primary pyrolysis products.

Unimolecular thermal decomposition of dimethoxybenzenes
The Journal of Chemical Physics, 2014The unimolecular thermal decomposition mechanisms of o-, m-, and p-dimethoxybenzene (CH3O-C6H4-OCH3) have been studied using a high temperature, microtubular (μtubular) SiC reactor with a residence time of 100 μs. Product detection was carried out using single photon ionization (SPI, 10.487 eV) and resonance enhanced multiphoton ionization (REMPI) time-

Thermal Decomposition of Thonzonium Bromide
Pharmaceutical Research, 1986Thonzonium bromide, a quaternary ammonium compound used as a surface active agent in a phenylephrine nasal solution, gave a gas chromatographic peak which was proportional in height and area to its concentration. Quaternary ammonium salts are nonvolatile and polar, thus the peak was attributed to a thermal decomposition product.

THE THERMAL DECOMPOSITION OF COMPLEX MOLECULES
Canadian Journal of Research, 1948Methylene diacetate, paraldehyde, and their homologues decompose in the gaseous state by a unimolecular mechanism at temperatures low enough to ensure the absence of free radical complications. The effect of molecular structure on the activation energies, frequency factors, etc., of these and other decompositions is discussed.
