โฆ Synopsis
The elcctrogenerative allylic oxidation of propylene to acrolein and acrylic acid has been demonstrated on a palladium anode in a 25 % phosphoric acid fuel cell. Open circuit c&l potentials of0.6 V and current densities as high as 5 mA cm --2 have been obtained but electrode inhibition results in a iower steady state current density of about 2 mAcm_' .
Selectivity to one particular product was poor and the influence of temperature and anode potential on product distribution remains unclear.

In an earlier short communication 1 it was reported that the partial electrochemical oxidation of a wide range of aliphatic hydrocarbons is possible in acetonitrile. These oxidations require a high positive potential, and hence the use of a tetrafluoroborate or a hexafluorophosphate as the base elec
The motivation for investigating the partial oxidation of propylene in subโ and supercritical water arises from the unique physicoโchemical properties of this medium. In subโ and supercritical water propylene oxide will react to 1,2โpropandiol, so this oneโstep process would be an alternative for th
