Sd. Jackson et La. Shaw, THE EFFECT OF BENZONITRILE ON THE HYDROGENATION OF PHENYLACETYLENE AND 1-PHENYL-1-PROPYNE OVER A PALLADIUM CARBON CATALYST/, Reaction kinetics and catalysis letters, 58(1), 1996, pp. 3-6
Benzonitrile reduces the rate of alkyne hydrogenation. However, it enh
ances the rate of styrene hydrogenation while reducing the rate of bet
a-methylstyrene hydrogenation.
