| Abstract: | The positive plate of Ni-Cd battery was
evaluated as Ni(OH)2/NiOOH electrode for the oxidation of six
aromatic and five aliphatic alcohols. In addition to galvanostatic preparative
electrolysis, cyclic voltammetric experiments were
also carried out. The anode material 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. |
