Abstract

This work presents the direct oxidative coupling of two molecules of acetylene to furan (C4H4O) over the surface of pure polycrystalline beta-UO3. For comparison, only traces of furan are formed over alpha-U3O8 and none on UO2 surfaces. A comparison to the reactions of other C-2 compounds (ethanol (H. Madhavaram and H. Idriss, J. Catal. 184, 553 (1999)), acetaldehyde (H. Madhavaram and H. Idriss, Catal. Today 63, 309 (2000)), and ethylene (H. Madhavaram and H. Idriss, J. Catal. 184, 553 (1999); H. Madhavaram and H. ldriss, Stud. Surf. Sci. Catal. 110, 265 (1997)) over beta-UO3 indicates the presence of two routes for making furan from C-2 compounds: one via aldolization and the other via oxidative coupling.
