Effect of water on alpha-methylstyrene hydrogenation on Pd/Al2O3
alpha-methylstyrene catalytic hydrogenation on Pd/Al2O3 is frequently used to characterize new reactors. However, whereas many authors report some problems of reproducibility or possible poisoning of the catalyst, no consistent advice is available in the literature to carry out the reaction without these problems. This work points out the inhibition of the reaction by trace amounts of water. An experimental procedure is explained to guarantee the reproducibility of the measures.
