Abstract: The reactions of ethane, propane, n-butane, isobutane and neopentane have been examined in the presence of deuterium on platinum films. Details of the products of exchange, hydrogenolysis and, where possible, isomerization are reported. The kinetic behaviour of the hydrogenolysis reaction showed a trend in that reactions of ethane were acceleratory, those of propane maintained a constant rate and those of molecules with four or more carbon atoms decelerated with time. The retardation in rates was much more mar… Show more

“…This interpretation is supported by molecular beam reactive scattering studies which revealed that dissociative deuterium chemisorption and H2-D2 exchange (2) occur over platinum with an activation energy very close to zeroll. Under our reaction conditions, there appears to exist only a small concentration of free sites located between adsorbed hydrocarbon species where deuterium is chemisorbed at low surface coverage.…”

“…The simultaneous hydrogenolysis and exchange of hydrocarbons C n H 2n +2 with n>1 have been studied by Dowie et al [26] on platinum films. From methane reaction, little additional mechanistic information was obtained from an analysis of the deuterium contents of the various molecules, as exchange is fast compared to hydrogenolysis or isomerization, leading to rapid isotopic equilibration.…”

“…This method of preparation is used to produce films of various metals. These systems provided a wealth of information on the periodic trend of catalytic activity for hydrogenation, dehydrogenation, and H/D exchange reactions [2]. These surfaces were often irreproducible and contained varying concentrations of surface defects.…”
