| Description |
The positive plate of Ni-Cd battery was evaluated as Ni(OH)
/NiOOH electrode for the oxidation of six aromatic and
2
five aliphatic alcohols. In addition to galvanostatic preparative electrolysis, cyclic volta mme tric experiments were
also carried out. The anode mate rial after electrolysis was evaluated using SEM and XRD. Except in the case of chlorine
substituted aromatic alcohols the nickel hydroxide electrode showed excellent stability even after the reuse for nearly
10-15 times. In 0.1 M KOH containing 67% tertiary butanol + 33% water as electrolyte, aromatic alcohols gave
predominantly aldehyde in good yield. In alkaline solutions without the co-solvent tertiary butanol aromatic alcohols were
oxidized to their corresponding carboxylic acids. Short chain aliphatic alcohol (C5) gave reasonable yield of carboxylic acid.
Long chain alcohols showed limited solubility in alkaline medium with and without co-solvent tertiary butanol and the
yields of carboxylic acids were also poor.
