Low pressure pyrolysis of 1-butanethiol.

Very Low Pressure Pyrolysis of Phenylacetic Acid

Recent reviews on the thermochemistry of organic radicals in the gas phase,'*2 have pointed out the necessity of a reassessment of the heat of formation of the hydroxycarbonyl radical and the corresponding bond-dissociation energy Ed in formic acid. Based on a re-evaluation of the early work of Back and S e h ~ n , ~ McMillen and Golden,' have recommended A,H('CO,H) = -209.2 kJ mol-'; however, ...

Conformationally specific vacuum ultraviolet mass-analyzed threshold ionization spectroscopy of alkanethiols: structure and ionization of conformational isomers of ethanethiol, isopropanethiol, 1-propanethiol, tert-butanethiol, and 1-butanethiol.

Conformational isomers of alkanethiols are isolated in the molecular beam, and the conformer-specific ionization dynamics have been investigated using vacuum ultraviolet mass-analyzed threshold ionization (MATI) spectroscopy. Only a single conformer of ethanethiol is observed to give the adiabatic ionization potential (IP) of 9.2922 +/- 0.0007 eV for the gauche conformer. For isopropanethiol, I...

Pyrolysis of Tobacco Residue: Part 1. Thermal

The pyrolysis of two types of tobacco residue was carried out at different pyrolysis temperatures between 300 and 600 °C and a residence time of 1 h in a nitrogen atmosphere. The effect of pyrolysis temperature on the product distributions was investigated and the composition of the bio-oils identified. The variation in product distribution depended on both the temperature and the type of tobac...

Low pressure adsorption of CO2 on multi-wall carbon nanotubes

Volumetric techniques were employed to study the adsorption of CO2 on a purified multi-wall carbon nanotubes (MWNT’s) sample, as a mesoporous material, at isothermal conditions of 288, 293 and 298 K and pressures ranging from 30 to 150 kPa. Langmuir, Freundlich and Sips equations were used to represent the isotherms. Also the parameters of these fitted isotherm models have been determined. The ...
