Embodiment 1
[0032] The method for preparing 3-(4-nitrophenyl)acrolein described in this embodiment comprises the following steps:
[0033] Get 5.0g (66mmol) of p-nitrobenzaldehyde and 10.0mL of acetaldehyde into the three-necked flask, add 10mL of 20% potassium hydroxide-methanol solution in the dropping funnel, stir magnetically, and cool the reaction with an ice-salt bath bottle, when the temperature drops to 0-5°C, slowly add 5mL potassium hydroxide-methanol solution dropwise under magnetic stirring, react for 40min, then add 5mL potassium hydroxide-methanol solution dropwise, continue to react at about 10°C for 40min, cool The reaction mixture solidifies below 5°C, add 16 mL of acetic anhydride, heat on a water bath for 30 min, pour into 120 mL of hot water, add 16 mL of concentrated hydrochloric acid, heat in a water bath for 20 min, and let stand for 24 h. Crystals were precipitated, filtered by suction, washed, and recrystallized in 30% aqueous acetic acid solution by mass fraction...
