In the former paper the authors examined experimentally the polarography of rancid fish-oil and obtained an interesting result.
Since the decemposition products of fats and oils are known to contain some volatile substances, so we examined in this report the application of polarography to the volatile compounds in rancid fats and oils.
The aeration method was used because the volatile substances are easily expelled by the air current and catched by the solution which works at the same times as the supporting electrolyte in the polarographic technique.
A chromatography on 2.4-dinitrophenylhydrazones of the volatile components has been carried out and the results were discussed of their relation to the above polarography.
