Solvated electron mobility in liquid tert-butanol

Abstract

The mobility μe of solvated electrons in liquid tert-butanol was estimated from the measured rate constant of the diffusion-controlled reaction [Formula: see text] combined with the measured molar conductivities of perchloric acid and ammonium perchlorate solutions; T = 300–330 K. The values μe = 4.1 × 10−8 m2 V−1 s−1 at 300 K and Eμ = 41 kJ mol−1 indicate that electrons migrate by a hopping mechanism in liquid tert-butanol. This contrasts with the ion-like diffusion mechanism of [Formula: see text] in methanol and ethanol. Keywords: tert-butanol, solvated electron, activation energy, mobility.
