Thermal decomposition kinetics of dicyclopentadiene-1,8-dione 7 implied an intramolecular competition between α,β-and β,γ-double bond to assist the CO elimination. Experimental thermolysis of 7 in dioxane gave 3a,7a-dihydro-1H-inden-1-one (cis-bicyclo[4.3.0]nona-2,4,7-triene-9-one), CO gas, and a very small amount of indanone. This result suggested...
Article
The rate coefficient of the gas-phase pyrolysis or elimination of exo-2-norbornyl formate was determined in a deactivated, static reaction vessel over the temperature range 300–350 °C and pressure range 41–105 Torr. The substrate exo-2-norbornyl formate yielded surprisingly exo-2-norborneol and CO gas. This reaction, in the presence or absence of t...
Article
The pyrolyses kinetics of 4- and 2-hydroxyacetophenones in the gas phase were determined in a static system, where the reaction vessel was deactivated with allyl bromide, and in the presence of the free radical inhibitor propene when necessary. The working temperature range was 464–485 °C, and the pressure range was 44–133 Torr. The reactions were...
Article
The gas-phase kinetics and mechanism of the homogeneous elimination of CO from butyraldehyde in the presence of HCl has been experimentally studied. The reaction is homogeneous and follows the second-order kinetics with the following rate expression: log k1 (s−1 L mol−1) = (13.27 ± 0.36) – (173.2 ± 4.4) kJ mol−1(2.303RT)−1. Experimental data sugges...
Article
Consecutive first-order, homogeneous intramolecular fluorine-chlorine exchange reactions of trichloro-(1,1-difluoroethyl)silane have been theoretically studied using ab initio post-Hartree-Fock G4MP2 and DFT (B3LYP, M06, M06-2X) levels of theory. The reactions were studied at 127 oC and 0.1 Torr of temperature and pressure respectively, yielding (1...
Article
Gas chromatography technique with flame ionization detector (GC-FID) has been employed for the quantification of methanol in diverse alcoholic drinks of legal (Cocuy, Superior and Antioqueño) and clandestine (Miche, Chuchuguaza and Cacique Arco de Palo) sale in Venezuela by using the internal standard method. Additionally, the ethanol content was q...
Article
The possible reaction mechanisms for the gas-phase thermal deamination of isopropylamine, tert-butylamine, and dextroamphetamine in the presence of hydrogen bromide are investigated by DFT calculations with several functionals. In each case, QTAIM analysis supports the formation of an ion-pair complex, which subsequently decays through a six-member...
Article
The gas-phase pyrolysis kinetics of tetrahydropyranyl phenoxy ethers: 2-(4-cyanophenoxy)tetrahydro-2H-pyran, and 2-(4-bromophenoxy)tetrahydro-2H-pyran were studied in a static system, with allyl bromide as surface-effect deactivator, and in the presence of toluene to inhibit chain reactions. The temperature and pressure were 350-440°C and 25-89 Tor...

The gas-phase elimination kinetics of tetrahydropyranyl phenoxy ethers: 2-phenoxytetrahydro-2H-pyran, 2-(4-methoxyphenoxy)tetrahydro-2H-pyran, and 2-(4-tert-butylphenoxy)tetrahydro-2H-pyran were determined in a static system, with the vessels deactivated with allyl bromide, and in the presence of the free radical inhibitor toluene. The working temp...
Article
Keto–enol tautomeric equilibrium and the mechanism of thermal conversion of 2- and 4-hydroxyacetophenone in gas phase have been studied by means of electronic structure calculations using density functional theory (DFT). A topological analysis of electron density evidence that the structure of keto and enol forms of 2-hydroxyacetophenone are stabil...
