This invention belongs to the field of chemical synthesis technology, specifically relating to a method for chiral separation of sec-butylcarb enantiomers. The invention employs high-performance liquid chromatography-mass spectrometry (HPLC-MS / MS) to separate sec-butylcarb enantiomers. The chromatographic column is a chiral column based on polysaccharide derivatives. Mobile phase A is an organic solvent, and mobile phase B is pure water. The volume ratio of mobile phase A:B is 20:80–50:50. The column temperature is 30–35 °C, gradient elution is used, and the flow rate is 0.3–0.6 mL / min. This invention provides a method for effectively separating chiral sec-butylcarb enantiomers, which has the advantages of high sensitivity, simple operation, and fast separation speed.
