An investigation is carried out of the effect of various process parameters on the kinetics and selectivity of the hydrogenation of dehydroisophytol in the presence of industrial supported palladium catalysts (0.75% Pd on ShAS silica gel; 0.5% Pd on ShN-2, P-5 silica gel) in a flow system by the streaming method. A basic schematic diagram of the continuous flow type apparatus incorporating this streaming method is shown. It is shown that the use of the above catalysts under staionary (fixed-bed) conditions significantly increases the productivity of the process 20-30 times, although they are noticeably inferior to the industrially used catalysts with respect to selectivity.
