The following are the laboratory synthesis steps and corresponding chemical equations for 4-aminoacetophenone:

1. Synthesis steps

Preparation of raw materials: Add aniline and ethanol to the reaction vessel and stir evenly.

Nitrification reaction: Drip concentrated nitric acid into the reactor under stirring, heat to around 80 ℃, and react for 3 hours. Then cool to room temperature and acidify with dilute hydrochloric acid to pH=5-6. Filter to obtain a yellow solid.

Hydrolysis reaction: Dissolve the yellow solid obtained above in water and add sodium hydroxide solution for hydrolysis reaction. After heating and refluxing for 2 hours, cool to room temperature and precipitate. Filter to obtain 4-nitrophenol.

Reduction reaction: Add 4-nitrophenol to the reaction vessel, add zinc powder and hydrochloric acid, heat to around 90 ℃, and react for 3 hours. Then cool to room temperature, filter to obtain product.

2. Chemical equation

Reaction of aniline with ethanol: C6H5CH2CH2OH+HNO3 → C6H5CH(CH3)NO2+H2O

Nitrification reaction: C6H5CH(CH3)NO2+HNO3 → C6H5CH(CH3)N2O+H2O

Hydrolysis reaction: C6H5CH(CH3)N2O+NaOH+H2O → C6H5CH(CH3)OH+N2O ↑+2NaOH

Reduction reaction: C6H5CH(CH3)OH+Zn+2HCI → C6H5CH(CH3)COOH+ZnCl2+H2O
