An effective method, use of a 2,4-dinitrophenylhydrazine (DNPH) derivatization and high-performance liquid chromatography (HPLC) with ultraviolet (UV) detection, has been used for separation carbonyl compounds. In particular, acetonitrile/water composition as a mobile phase could not separated acrolein/acetone and 2-butanone/ butyraldehyde. In this study, however, that"s compounds separated using acetonitrile/water/tetrahydrofuran as a mobile phase. The resolution was 1.48 and 1.46, respectively. Also, aldehydes and ketones was shown different decrease rate and increase resolution at increase tetrahydrofuran ratio. But butyraldehyde become coeluted methacrolein.
Therefore, it is need to consider of mobile phase for separation of butyraldehyde.
