Thermal Decomposition of Norbornane (bicyclo[2.2.1]heptane) Dissolved in Benzene:  Experimental Study and Mechanism Investigation

Abstract

The thermal decomposition of norbornane (dissolved in benzene) has been studied in a jet stirred reactor at temperatures between 873 and 973 K, at residence times ranging from 1 to 4 s and at atmospheric pressure, leading to conversions from 0.04 to 22.6%. 25 reaction products were identified and quantified by gas chromatography, amongst which the main ones are hydrogen, ethylene and 1,3-cyclopentadiene.A mechanism investigation of the thermal decomposition of the norbornane -benzene binary mixture has been performed. Reactions involved in the mechanism have been reviewed: unimolecular initiations 1 by C-C bond scission of norbornane, fate of the generated diradicals, reactions of transfer and propagation of norbornyl radicals, reactions of benzene and cross-coupling reactions.

Biodiesel: a green polymerization solvent

“…30 However, long reactions at high temperatures may result in complementary decomposition reactions of FAME. 31 A high degree of chain transfer to solvent when using FAME as the polymerization medium will lead to lower molecular weight polymer products, which may be desirable in some product applications.…”

Experimental and kinetic modeling study of the pyrolysis and oxidation of 1,5-hexadiene: The reactivity of allylic radicals and their role in the formation of aromatics

“…The applied experimental setup is an isothermal quartz jet-stirred reactor with a dedicated feed section and analysis section for outlet gases. The main features of the apparatus are discussed below, details can be found elsewhere [31,32].…”

Hydrocarbons Heterogeneous Pyrolysis : Experiments and Modeling for Scramjet Thermal Management

“…This may be related to uncertainties on kinetic parameters of reactions involved in the formation of benzene (C 5 -pathway) and poly-aromatics compounds. To expand our knowledge on the pyrolysis of other hydrocarbons, some cyclanes (cyclopentane, cyclohexane and norbornane) were also studied in our jet-stirred reactor 5 .…”
