실험 절차
4-Chlorophenylhydrazine hydrochloride (5.0 g) and 3.4 g of sodium acetate were dissolved in a mixture of 50 ml of water and 25 ml of ethanol, to which 1.69 g of 80% acetaldhyde aqueous solution were added dropwise at room temperature, and the resulting mixture was stirred for 30 minutes at room temperature. After adding 50 ml of water, the reaction mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated sodium chloride solution, dried and distilled off to give acetaldehyde 4-chlorophenylhydrazone as an oil.
