This paper describes the anodic oxidn. of various aliph. alcs. in pure water using a Nafion cation exchange membrane as a solid polymer electrolyte. The oxidn. was carried out on an IrO2 anode under conditions of simultaneous O2 evolution. The exptl. results for the anodic oxidn. of 4 different alcs. (iso-PrOH, PrOH, EtOH and MeOH) agree well with the theor. model presented in a previous paper. Finally, a simple exptl. method is described for the detn. of the relative reactivity of oxidn. of orgs. on IrO2 anodes. [on SciFinder (R)]
