# Thermal decomposition of norbornane (bicyclo[2.2.1]heptane) dissolved in benzene. Experimental study and mechanism investigation

## TL;DR

This study investigates the thermal decomposition of norbornane in benzene using experimental data from a jet stirred reactor, identifying reaction products and proposing a detailed reaction mechanism involving radical reactions and bond scissions.

## Contribution

It provides new experimental data and a comprehensive mechanism for norbornane decomposition in benzene at high temperatures.

## Key findings

- Identified 25 reaction products including hydrogen, ethylene, and 1,3-cyclopentadiene.
- Quantified conversion rates from 0.04% to 22.6% at 873-973 K.
- Proposed detailed reaction pathways involving radical reactions and bond scissions.

## 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.
