The authors have studied the kinetics and selectivity of the hydrogenation of ..beta..-ionone over supported stationary palladium catalysts (0.5% Pd/ZnO, 0.75% PdShAS, 0.5% Pd/ShPAK, P-5, P-15) in a flow-through reactor by a streaming method in relation to different factors: hydrogen pressure, reaction temperature, rate of addition of reactants, and rate of bubbling of excess hydrogen. It can be concluded that modification of the palladium catalyst with cobalt increases the selectivity of the process and the predominant direction of the reaction is the formation of dihydro-..beta..-ionone.
