L. Forni et al., DESORPTION PARAMETERS IN THE SYNTHESIS OF 2-METHYLPYRAZINE OVER ZN-CR-O, Reaction kinetics and catalysis letters, 49(2), 1993, pp. 271-278
Desorption activation energy of both reactants and products was found
to be only slightly higher than the desorption enthalpy and, for react
ants, it was higher than the activation energy for the title reaction.
Methylpyrazine desorbs much more easily than reactants.
