Ring opening of ehtylcyclopentane over supported Pt catalysts

Ring opening of ethylcyclopentane (ECP) was studied over 6.3% Pt/SiO2 (EUROPT-1) and 10% Pt/Al2O3, as a function of the hydrogen pressure. Both catalysts gave almost nonselective ring opening. Pt/Al2O3 produced also olefins, more side dealkylation and less fragmentation products. It is likely, that adlineation sites are operative over both catalysts.
