Questions And Answer | Back Directory | [Synthesis]
Dissolve 218 g of p-nitrobenzyl acetate in 500 ml of hot methanol, stir, and slowly add 380 g of 15% sodium hydroxide solution. After the addition was completed, it was placed for 5 minutes, and then poured into ice water to precipitate a precipitate. The filtered precipitate was decolorized with activated carbon in hot water, and recrystallized to give p-nitrobenzoicacidhydrazide 110-121 g . |
