Abstract

original image

Unvollständige Verkokung sulfoaromatischer Kohlenwasserstoffe führt zu einem Kohlenstoffmaterial aus kleinen polycyclischen aromatischen Kohlenstoffschichten mit SO3H-Gruppen (siehe Bild). Diese unlösliche feste Säure vermittelt sehr effizient die Bildung von Ethylacetat, die Hydrolyse von Cyclohexylacetat und die Hydratisierung von 2,3-Dimethyl-2-buten.
