Synthesis of 2,6-dichlorobenzaldehyde

Preparation of 2,6-dichlorobenzaldehyde

2,6-dichlorobenzaldehyde is prepared similarly to 2-chlorobenzaldehyde by hydrolyzing 1,3-dichloro-2-(dichloromethyl)benzene in acidic medium. Hydrolysis is carried out at a temperature of 50-55 ° C. During steam distillation cooling must not be applied because the aldehyde at a temperature of 70-71 ° C solidifies. The product was filtered on Buchner funnel and dried on filter paper. Yield: from 250 g of 1,3-dichloro-2-(dichloromethyl)benzene obtained 160 g (84% of theory) of crystalline 2,6-dichloro-benzaldehyde. The product has a pungent odor.
