Js. Do et Yl. Do, INDIRECT ANODIC-OXIDATION OF BENZYL ALCOHOL IN THE PRESENCE OF PHASE-TRANSFER CATALYST IN A CSTER - EFFECT OF CURRENT-DENSITY, ORGANIC-TO-AQUEOUS VOLUME RATIO AND CONCENTRATION OF PHASE-TRANSFER CATALYST, Electrochimica acta, 39(15), 1994, pp. 2311-2319
The effects of current density, organic-to-aqueous volume ratio (R(v))
and concentration of phase-transfer catalyst on current efficiency, c
onversion of benzyl alcohol, yield and selectivity of benzaldehyde, po
wer consumption, and induction period were systematically studied in t
his work. The current efficiency of the oxidation of chloride ion to h
ypochlorite ion were evaluated as 62.0 and 65.0%, respectively, when R
(v) was 1.0 and 2.0. The current efficiency for production of benzalde
hyde was indicated by the experimental data as having decreased at a h
igh organic how rate (2.0 ml min(-1)) when the concentration of phase-
transfer catalyst decreased, and the current density and R(v) increase
d. The conversion of benzyl alcohol and yield of benzaldehyde increase
d, and the selectivity of benzaldehyde decreased at a high organic flo
w rate when both the current density and the concentration of phase-tr
ansfer catalyst increased. The power consumption was confirmed by the
experimental results as having decreased when the current density decr
eased and the concentration of phase-transfer catalyst increased.
