Polarographic behaviour of some o-hydroxyketoximes.
The polarographic behaviour of three o-hydroxyketoximes, CH(3)C(6)H(3)(OH)CRNOH, where R CH(3), C(2)H(5) and C(3)H(7), has been studied in 5% ethanolic medium, with potassium chloride as supporting electrolyte. A single four-electron reduction wave is obtained which diminishes with increase in pH, being replaced by a new wave in alkaline media. A trough is formed on the limiting-current plateau at higher negative potentials. A mechanism has been proposed for the reduction at the dropping mercury electrode.
