Webb20 mars 2004 · The propyne and propylene oxidation temperatures on the Pt film are quite similar to the Pt(1 1 1) surface. Propyne adsorbs on the 100 Å Pt/Al 2 O 3 thin film through the π system nearly parallel to the surface, in a manner very similar to the Pt(1 1 1) surface. However, molecular adsorption of propylene on the Pt film surface is more complex. WebbThe reaction principle was originally applied for the production of ethylene from propene and was developed in the 1960s by Phillips (Triolefin process). In this process, propene …
