Descripción
In this paper are reviewed some research works dedicated to the study of
carbonaceous dust and molecules of astrochemical interest. First of all
it is discussed the carbon arc through which it is possible to produce
carbon soot and fullerenes under helium but also many other different
products just changing the arcing conditions. For example, when the
carbon arc is struck in an hydrocarbon solvent it is possible to produce
and trap polyynes in the solvent. Monocyanopolyynes and dicyanopolyynes
can be produced as well by selecting the appropriate conditions.
Amorphous carbon soot or partially graphitized carbon black can be
produced with the carbon arc. Fullerenes were found in space thanks to
the reference infrared spectra and the absorption cross sections which
were determined in laboratory. Fullerenes are readily reactive with
hydrogen yielding fulleranes the hydrogenated fullerenes. Furthermore
fullerenes react with PAHs and with iron carbonyl yielding adducts. All
these fullerene derivatives were synthesized and their reference spectra
recorded in laboratory. It was proposed that petroleum fractions can be
used as model substrates in the explanation of the carriers of the AIB
(Aromatic Infrared Bands) observed in protoplanetary and planetary
nebulae and the UIE (Unidentified Infrared Bands) found in the
interstellar medium.
