| Abstract：A capillary GC method for the determination of the materials and products in the preparation of chlorobenzaldehyde from benzaldehyde was introduced. The range of linearity were 7.3～130.3mg for benzaldehyde and 10.7～168.2mg for chlorobenzaldehyde, with correlation coefficient 0.9990 over, RSD less than 1.5% and the recovery 99.5%～101.3%. |
| Key words：chlorobenzaldehyde; benzaldehyde; capillary column GC |
