Dioxins and furans in fly ashes from an incinerator

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2004
The amount of dioxins and furans in fly ashes from a medical waste incinerator was determined following the US EPA 8280A protocol. Dioxin emissions in both particulate matter and exit gas stream from the incinerator’s chimney were estimated. Furthermore,

Photooxygenation of furans in water and ionic liquid solutions [PDF]

open access: yes, 2009
Photooxygenation of differently functionalized furans is investigated in aqueous solutions and in ionic liquids [emim]Br and [bmim]BF4. The reaction is generally selective and the final products derive from rearrangement of the intermediate ...

Highly-functionalised difluorinated cyclohexane polyols via the Diels–Alder reaction : regiochemical control via the phenylsulfonyl group [PDF]

open access: yes, 2005
A difluorinated dienophile underwent cycloaddition reactions with a range of furans to afford cycloadducts whichcould be processed regio- and stereoselectively via episulfonium ions, generated by the reaction between their alkenyl groups and ...

(Furan-2-yl)[(furan-2-yl)carbonyldisulfanyl]methanone [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2011
The mol-ecule of the title compound, C(10)H(6)O(4)S(2), has crystallographically imposed twofold symmetry. The dihedral angle formed by the furan rings is 80.90 (8)°. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds into chains running parallel to the a axis [C-S-S-C torsion angle = 82.04 (11)°].
