Gas-liquid chromatographic analyses

The gas chromatography of methyl and chloromethyl esters of pivalic, 2-methylbutyric, isovaleric and valeric acid and certain of their monochloro derivatives was studied. Separation of the combined mixtures of methyl and chloromethyl esters was better on Carbowax 20M than on SE-30. The retention tim... Ausführliche Beschreibung

520 |a The gas chromatography of methyl and chloromethyl esters of pivalic, 2-methylbutyric, isovaleric and valeric acid and certain of their monochloro derivatives was studied. Separation of the combined mixtures of methyl and chloromethyl esters was better on Carbowax 20M than on SE-30. The retention times of esters with subtituents adjacent (i.e. at C-2) to the carboxyl group appear to be sensitive to column polarity, particularly in the case of the chloromethyl esters. The retention order and relative retention times of compounds are discussed.
