SUMMARY Volatile monocarbonyls produced by mildly oxidized esters of oleic, linoleic, linolenic acids and fats have been characterized by paper chromatography of 2,4‐dinitrophenylhydrazone derivatives. The unsaturated fatty acid esters yielded a total of 7 n ‐alkanals, 8 n ‐alk‐2‐enals, and 4 alk‐2,4‐dienals; and similar results were obtained with the fats. Each unsaturated acid produced three major characteristic aldehydes. Comparisons of esters and glycerides showed the presence of keto or aldehyde ester scission products.
