12. Figure 2b only shows the results for the first 2 h of reaction to magnify the initial reaction rate differences. The experiment with no ethanol age went to complete conversion in 10 h.
13. After 30 min, both hydrogenations in Figure 3 were stopped, the headspace was purged with nitrogen, and 20 psig air was injected. There was no effect of air exposure on the reaction rate in the absence of the ethanol age. The complete data set, in the form of a reaction rate profile, including the effect of air exposure is shown in Figure 4B with an explanation in the text.
