반응 단계
158.5 g (1 mol) of a mixture of 56% of 4-chloro-2-fluoro-benzaldehyde and 44% of 2-chloro-4-fluorobenzaldehyde were heated together with 700 g of sulfolane and 75 g (1.29 mol) of potassium fluoride at 215° C. for 10 h. The working up was carried out as in Example 1. 99.5 g of 2,4-difluorobenzaldehyde equivalent to 70% of the feed-stock was obtained.
