摘要：
Under boiling and refluxing conditions, cyclooctane has been dehydrogenated to cyclooctene and molecular hydrogen selectively with carbon- and alumina-supported Pd, Ph, and Ru catalysts. The activity order among these metal catalysts was Pd > Rh > Ru. The most active carbon-supported Pd catalyst was least sensitive to the rate retardation caused by cyclooctene adsorption. Desorption of molecular hydrogen from the Pd catalyst surface was deduced to proceed rapidly after the rate-determining step.
