Electrochemistry in Near-Critical and Supercritical Fluids. 6. The Electrochemistry of Ferrocene and Phenazine in Acetonitrile between 25C and 300C.

Abstract

Cyclic voltammetry in MeCN at various temperatures and pressure, including supercritical conditions, are described. The reduction wave of phenazine in MeCN/CF3SO3Na was reversible or nearly reversible up to 200 C. Above 200 C the second reduction wave coalesced with the first. The oxidation of ferrocene in CH3CN was quasi-reversible between 25 and 285 C. Above the critical temperature (Tc) the standard heterogeneous electron transfer (k) decreased. The diffusion coefficients (D) of phenazine and ferrocene up to Tc are reported, and the determination of viscosity of high temperature/high pressure liquids and fluids based on the measurements of D via and Stokes-Einstein equation is suggested.
