Thereafter, a mixture of 1,000 ml of distilled water, 500 ml of methanol, 50 ml (59.7 g; 0.62 mole) of concentrated hydrochloric acid and 350 g (0.98 mole) of (E)-2-(4-chlorophenyl)-1-(2,4-dichlorophenyl)-3,3-dimethoxyprop-1-ene (I) is refluxed for 4 hours, while stirring. The mixture is cooled to room temperature and 1,000 ml of water are then added, while stirring. 300 g (0.96 mole; 98% of theory) of (E)-2-(4-chlorophenyl)-3-(2,4-dichlorophenyl)-acrolein are isolated in the form of pale yellowish crystals of melting point 106°-109° C.
