The Investigation of Propane Oxidation Using Electrochemical Mass Spectrometry.

Abstract

The properties of propane and propane-2-C13 adsorbates formed at 0.25 V vs. the polarized hydrogen electrode (0.274 vs. RHE) were examined using electrochemical mass spectrometry (EMS). Experimental results indicate the presence of adsorbable organic impurities which compete with propane for adsorption sites. Based on the time dependence of inhibition of hydrogen adsorption, the impurity level appears comparable to that of earlier workers. All of the C(13)C2H8 adsorbed can be accounted for on the basis of products desorbed at either 0.05 V (propane and ethane) or at large anodic potentials (carbon dioxide). The results support the view that (1) propane formed on cathodic desorption arises from the original carbon skeleton of the absorbable propane and (2) methane produced at 0.25 V is produced with equal probability from all carbons in the original propane.
