Resumen
[EN] The behavior of activated carbon in many catalysis processes is determined by the basic character of its surface.
Using FT-IR spectroscopy, an attempt is made here to identify not only pyrone and chromene type structures but also their
isomers in a commercial activated carbon (Merck; AC). The infrared analysis between 400 and 4000 cm−1 focuses on the keto
(−CO) group in pyrones, methylene (−CH2−) group in chromenes, and enol ether group (O−CC) in both kinds of
structures. Although overlapping bands are frequent in the AC spectrum, occurrence of most significant pyrone and chromene
absorptions proves their presence in AC. This is so in particular for 2-pyrone and 4H-chromene, whereas 4-pyrone is less
amenable to the infrared analysis.
