Abstract
The competitive catalytic hydrogenation of 2-octyne and 1-heptene in methanol has been studied on catalysts 3% Pd on activated carbon and Pd black, modified with ammonium chloride, potassium chloride, potassium carbonate, or calcium carbonate. The rates of hydrogenation of the two substrates and the rate of isomerization of 1-heptene have been determined. The effect of inorganic salts on the activity and selectivity of the catalysts is discussed.
