Abstract

A silicon carbide microtubular reactor has been used to measure branching ratios in the thermal decomposition of furan, C4H4O. The pyrolysis experiments were carried out by passing a dilute mixture of furan (approximately 0.01%) entrained in a stream of helium through the heated reactor. The SiC reactor (0.6 mm i.d, 2 mm o.d., 2.5 cm long) operates with continuous flow. Experiments were performed with a reactor inlet pressure of 100-300 Torr and a" chemical temperature" within the reactor of 1000-1400 K; characteristic residence times in the reactor are 100-200μsec. Tunable synchrotron radiation photoionization mass spectrometry was used to monitor the products, measure the branching ratio of the two carbenes as well as the ratio of [HCCCH2]/[HC≡CCH3]. The results of experiments clearly demonstrate a preference for the decomposition channel through theβ-carbene. At temperatures of 1000-1100 K, only HC≡CCH3 is produced. As the temperature rises to 1300-1400 K, roughly 10% of the flux through theβ-carbene channel goes to HCCCH2 radicals.
