Abstract

Benzaldehydes are produced by heating the corresponding benzal chloride containing less than 1% anhydrous ZnCl2 to above 100 DEG C. (preferably 105 DEG C.-135 DEG C.) and adding water at substantially the rate at which it reacts with the benzal chloride. In examples (1) benzaldehyde is obtained from benzal chloride and (2) o-chlorobenzaldehyde from o - chlorobenzalchloride, p-Chloro- and 2 : 6-dichloro-benzaldehydes, and o-, m- and p-tolualdehydes are also mentioned.
