Graphical Abstract
Hot Spots: Die überraschende, offenbar katalytische Wirkung von H2 bei der Dehydrierung von 1 in überkritischem CO2 ist das Ergebnis thermischer Hot Spots (siehe Thermobild des Reaktors), die zu Beginn im Katalysatorbett durch eine exotherme Hydrierung erzeugt werden. Dieses punktuelle Erhitzen erzwingt die Dehydrierung und ermöglicht einen einfachen Zugang zu Dien 2.

- 33The residence time was estimated by calculating the velocity of the fluid passing through the reactor per unit volume. Fluid velocity (m s−1) was calculated at experimental temperature and pressure, and therefore requires specific data, which was obtained from appropriate equations of state, in this case from the NIST database (http://www.nist.gov).
