Indene (C9H8) aromatic hydrocarbon growth was studied in a flow reactor. Researchers identified pathways forming larger aromatic molecules like chrysene and naphthalene, highlighting resonance-stabilized radical roles.

Area of Science:

  • Chemical kinetics
  • Combustion chemistry
  • Organic chemistry

Background:

  • Aromatic hydrocarbons are key components in combustion and industrial processes.
  • Understanding the formation pathways of polycyclic aromatic hydrocarbons (PAHs) is crucial for controlling emissions and designing processes.
  • Indene, a molecule containing a cyclopentadienyl moiety, serves as a model compound for studying aromatic growth.

Purpose of the Study:

  • To experimentally investigate the aromatic hydrocarbon growth from indene (C9H8).
  • To identify major products and propose reaction pathways for indene conversion.
  • To elucidate the role of resonance-stabilized radicals in aromatic condensation.

Main Methods:

  • Experimental investigation using a 4-second flow reactor.

  • Temperature range studied: 650-850 degrees C.
  • Product analysis and identification of C18H12, C17H12, and C10H8 isomers.
  • Thermochemical modeling using semi-empirical molecular orbital methods.

    • Main Results:

    • Major products identified include C18H12 isomers (chrysene, benz[a]anthracene, benzo[c]phenanthrene), C17H12 isomers (benzo[a]fluorene, benzo[b]fluorene), and C10H8 isomers (naphthalene, benzofulvene).
    • Two primary reaction pathways were proposed: intramolecular addition leading to C17H12 and C10H8 products, and beta scission forming biindenyl which leads to C18H12 products.
    • Temperature dependencies influenced both pathway partitioning and product isomer distributions.

    Conclusions:

    • Resonance-stabilized indene radical intermediates play a significant role in aromatic growth.
    • Two distinct reaction routes, rearrangement and beta scission, dictate the formation of different product classes.
    • The findings contribute to understanding aromatic condensation mechanisms in systems containing cyclopentadienyl moieties.
