Reactions of polycyclic alkylaromatics: Structure and reactivity

Volatile organic compounds (VOCs) in soil gases from Solfatara crater (Campi Flegrei, southern Italy): Geogenic source(s) vs. biogeochemical processes

“…Thermal decomposition can also contribute to the degradation of aromatic compounds (Savage and Klein, 1987;Smith and Savage, 1991) especially in hydrothermal environments (McCollom et al, 2001). Benzene is considered recalcitrant to both biodegradation and abiotic decomposition processes with respect to the alkylated aromatic compounds (Horowitz et al, 1982;Hutchins et al, 1991;Heider et al, 1998).…”

Retardation of oil cracking to gas and pressure induced combination reactions to account for viscous oil in deep petroleum basins: Evidence from oil and n-hexadecane pyrolysis at water pressures up to 900 bar

“…The cracking of aromatic compounds has been investigated (Savage and Klein, 1987;Freund and Olsmtead, 1989;Poutsma, 1990;Smith and Savage, 1991;Burnham et al, 1998;Yu and Eser, 1998;Behar et al, 1999;Bounaceur et al, 2000;Burklé-Vitzthum et al, 2003;2004;Dartiguelongue et al, 2006;Leininger et al, 2006). The thermal stability of alkylaromatics depends on the number of aromatic rings and length of the side chain (Smith and Savage, 1991;Behar et al, 2002).…”

“…The thermal stability of alkylaromatics depends on the number of aromatic rings and length of the side chain (Smith and Savage, 1991;Behar et al, 2002). The main degradation products appear to be a combination of heavy aromatics (e.g.…”

Combustion and pyrolysis reactions of alkylated polycyclic aromatic compounds: The decomposition of 13C methylarenes in relation to diesel engine emissions

“…A similar situation holds for the reactions of 1-methylnaphthalene and 9-methylphenanthrene; they have similar enthalpies and the data available suggests that the reaction rates are similar [19,29,35]. The reactions that occur at engine combustion temperatures thus initially lead to H-abstraction and subsequent decomposition of the aromatic ring compounds.…”

“…The definitive early work on the mechanism was by Smith and Savage [18,29] This would lead to products which are largely determined by their thermodynamic stability [30,31] although this depends on the rate of the cooling process in the exhaust system…”
