Abstract
Abstract Continuous flow pyrolysis (CFP) of furan (1), benzo[b]furan (2) and dibenzofuran (3) has been investigated at 900°C. Complete decomposition of 1 and 2 was observed, while 3 proved to be more temperature resistant. In the pyrolysates of 1–3, up to 22 different products were identified by GC-MS, 12 of these are identical. Mainly polycyclic aromatic hydrocarbons (PAHs), such as naphthalene (11) (6–28%), phenanthrene (17) (2–25%), biphenyl (22) (1–11%), pyrene (18) (1–10%), benzopyrene (19) (1–10%), fluoranthene (20) (3–9%), triphenylene (21) (3–9%), acenaphthylene (13) (1–6%), anthracene (23) (1–6%) and fluorene (12) (1–3%), were obtained. Only from 3, small amounts of larger oxygen containing polycyclic hetarenes (PHAs), such as benzo[b]naphtho[2,3-d]furan (37) and benzo[1,2-b:4,5-b′]bis[1]benzofuran (36), are generated as additional products besides PAHs.
