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.
