Chemisorption of Propane on Platinum Surfaces in the Presence of Pre-adsorbed Water

THE chemisorption of saturated hydrocarbons on platinum surfaces has been studied by several authors1–3, whose results imply that chemisorption of hydrocarbons is accompanied by extensive dissociation of the molecule, at least at temperatures above 80° C (ref. 3). It is assumed that some C–C and much C–H is dissociated at temperatures of about 100° C.
