Journal ArticleDOI

Simulated kinetics of the atmospheric removal of aniline during daytime.

TL;DR: Under atmospheric conditions, the reaction of OH radical with AN and the subsequent reactions with O2 molecules are investigated and the results indicate that the majority of O2 addition goes to the anti-directions with a branching ratio of 97.7% and produces the bicyclic peroxy radicals (BPRs) that can react with NO radical to form bicyclic alkoxy radical (BARs).
Journal ArticleDOI

Thermochemistry and Kinetics of the Thermal Degradation of 2-Methoxyethanol as Possible Biofuel Additives.

TL;DR: This work investigates the unimolecular thermal degradation of 2-methoxyethanol using DFT/BMK and ab initio methods and finds that production of methoxyethene via 1,3-H atom transfer represents the most kinetically favored path in the course of 2ME pyrolysis at room temperature and requires less energy than the weakest Cα − Cβ simple bond fission.
Journal ArticleDOI

Computational Studies on the Thermodynamic and Kinetic Parameters of Oxidation of 2-Methoxyethanol Biofuel via H-Atom Abstraction by Methyl Radical

TL;DR: In this work, a theoretical investigation of thermochemistry and kinetics of the oxidation of bifunctional 2-Methoxyethanol (2ME) biofuel using methyl radical was introduced and calculations show that energy barriers for n-butanol oxidation increase in the order of α ‹ O ‹ ϒ ‹ β ‹ ξ, which are consistent with previous data.
Journal ArticleDOI

A computational study on the kinetics of pyrolysis of isopropyl propionate as a biodiesel model: DFT and ab initio investigation

TL;DR: In this article, a computational kinetic study on the pyrolysis of isopropyl propionate (IPP) as a biodiesel model using density functional theory (DFT), namely ωB97XD and M06-2X levels, was performed.
Journal ArticleDOI

Thermo-kinetic theoretical studies on pyrolysis of dimethoxymethane fuel additive

TL;DR: In this article, the authors reported a thermo-kinetic investigation of DMM pyrolysis in temperature range 300-2000k using M06-2X and ωB97XD density functional methods and modest cost ab initio/complete basis set-quadratic Becke3 (CBS-QB3) procedure.
