nitrogen at a 150 cc/min flow rate. The flask is
inserted into an oil bath at 80 °C and the reaction
slurry is stirred. After stirring for 24 hours, the
slurry is transferred to a roto-vap and the water is
removed by roto-evaporation under vacuum at 50 °C. The
solid catalyst is then dried at 60 °C in a vacuum oven
for 24 hours. Measured Pd loading of the catalyst is
0.40 wt.% and the measured Au loading is 0.09 wt.%.
Contrastingly, the catalyst employed in the Example 7
reaction test was prepared by a method that differed by more than
the lack of simultaneous gold and palladium addition from the
catalyst employed in Example 4 as evident by the use of different
metal salts in different amounts, much shorter stirring times,
and a hydrogen reduction step. See Examples 5 and 6 of the
specification for the manner of preparing the catalyst used in
Example 7. Not only is a catalyst composition that differs by
more than the order of addition of palladium and gold used in
Example 7 (as compared to the catalyst used in Example 4), but
the reaction test employed in Examples 4 and 7 differ.
For example, the relative amounts of propylene, hydrogen and
oxygen employed in Examples 4 and 7 were not the same. Also, the
pressure employed during the reactions of Example 4 and 7
differed. Moreover, in Example 4 both gas and liquid phase
products are analyzed whereas in Example 7 only the exit-gas is
