| use | for organic synthesis. |
| production method | 250g(4.7mol) of nitrobenzene and 8L of water are vigorously stirred together, 620g(8.1mol) of 85% zinc powder are added in batches within 15-20min, the temperature in the reduction reaction is raised to 60-65 ℃, the reaction is completed, zinc oxide is filtered out while hot, the filtrate is saturated with salt (about 3kg of salt is required), and cooled to 0 ℃, crystallize out phenylhydroxylamine. The pure product was 275-300g with a yield of 62-68%. |
