Results Using propene as the reactant and 85% Hap04 at 100" as the electrolyte, greater than 99% conversion of propene into propane was observed when the reactant flowed over the working electrode at a rate of 0.02 mol/hr or 9 sec/cc. The potential difference between the working electrode and the dhe was found not to be important as long as it was cathodic to 0.03 V. There was no rapid decrease in conversion with time as, after 7 continuous hr ...
