Electrochemical hydrogenation of citral

2. The effect of the components of the medium on the process of electrochemical reduction at a copper cathode

Russian Chemical Bulletin Aims and scope

Abstract

The factors (concentration of citral, composition of the solvent, AcOH ∶ citral ratio) affecting electrochemical hydrogenation of citral at an annealed copper cathode have been determined. The highest total yield (94 %) of the alcohols (nerol, geraniol, citronellol) with a considerable predominance of the latter is achieved at 40 % DMF in water, citral concentration 0.02M, and AcOH ∶ citral ratio=10∶1. The transition to purely organic or purely aqueous media leads to a decrease in both the total yield of the alcohols and the selectivity of the process.
