The kinetics of diacetyl monoxime(DAM) hydrogenation catalyzed by Pd/PPh-3 has been studied. The reaction follows the second order kinetics with respect to DAM in the range of investigation, the zeroth order kinetics with respect to H-2 pressure in optimum reaction conditions, and the first order kinetics with respect to catalyst concentration. The kinetic equation of hydrogenation reaction rate obtained is { r =} k [DAM]+2[Cat.]. The activation energy for this reaction is E a=50.41 kJ·mol+{-1}. The drawn up mechanism of reaction is in agreement with experimental results.
