A simple, rapid method employing sulfuric acid and water to regenerate earbonyl compounds from 2,4‐dinitrophenylhydrazones is presented. The method was evaluated by using a number of DNP‐hydrazones of alkanals, alkan‐2‐ones, and 2‐alkenals and was found to give recoveries ranging from 23 to 61%. The procedure makes possible rapid organoleptic observations and is well adapted for recovery of the free carbonyl compounds for other studies.
