This paper deals with the process analysis of asymmetric transfer hydrogenation of acetophenone by using Chiral capillary gas chromatography. The solvents, acetophenone and phenylethanol enantiomers were wellseparated on a Chrompack CPcyclodextrinβ236M19 column with FID detector. The racemic phenylethanol was determined and the relative content of the enantiomer was 50.1∶49.9(n=6). The chromatographic separation enable accurate determination of e.e. value and conversion(%) of acetophenone. The absolute configuration of the major enantiomer of phenylethanol was determined from the elution order. This method may be suitable for research in process of asymmetric transfer hydrogenation of arometic ketones.
