Abstract
A method for the quantitative conversion of traces of aldehydes and ketones to their 2,4-dinitrophenylhydrazones at room temperature is presented. The 2,4-dinitrophenylhydrazones of a number of aliphatic aromatic carbonyl compounds have been prepared. The compounds were separated on a reversed-phase μBondapak C18 column. The method is valuable in the quantitative determination of traces of low-molecular-weight aldehydes and ketones. Derivatives of identical molecular weight can be easily separated by high-pressure liquid chromatography but not by gas chromatography under the conditions tried.
