The competitive catalytic hydrogenations of pairs of 2,5-dimethyl-2,4-hexadiene with 1-heptene and 2-octyne with 1-heptene were studied on palladium black modified with lead or thallium to various degrees of coverage. The dissolved and adsorbed hydrogen was determined electrochemically and the selectivities of the competitive hydrogenations were established. The effect of the lead or thallium ad-atoms on the hydrogenation kinetics is discussed.
