Method for the preparation of α,α, α′,α′-tetrachloro-p-xylene
A synthesis method of α,α,α′,α′-tetrachloro-p-xylene is disclosed. The method includes reacting terephthaldicarboxaldehyde with a mixture of SOCl2 and dimethylformamide (DMF) to obtain a product mixture containing α,α,α′,α′-tetrachloro-p-xylene as a major product and 4-dichloromethyl benzaldehyde as a side product, which can be separated by silica column chromatography.
