Study on the synthesis of chloro-benzaldehyde

In thsi paper,the synthetic methods of o chlorobenzaldehyde,p chlorobenzaldehhyde,2,4 dichlorobenzaldehyde,2,4,6-trichloro-benzaldehyde in the chlorobenzaldehyde have been studied.Then explored the new synthetic method of chloro-benzaldehyde by chloro-aniline,studied on the influences of the substituted benzaldehydes,with different position and number to productivity of chloro-benzaldehyde.Discussed the factors influencing reactions.
