| production method | 1. Iron powder reduction method with 2, 5-dichloronitrobenzene as raw material, in dilute acid medium with iron powder reduction, after neutralization, separation, refined to get the finished product. 2. Hydrogenation reduction method with 2, 5-dichloronitrobenzene as raw material, ethanol as medium and catalyst, hydrogenation reaction is carried out under heating and pressure, and the reaction product is separated and refined to obtain a finished product. The preparation method is to add 2, 5-dichloronitrobenzene, ethanol and platinum catalyst in the autoclave, and introduce hydrogen to 3 ~ 4MPa at 85~90 ℃, then, hydrogen gas supply was stopped and the heat preservation was carried out. The end point was reached when the pressure decreased and stabilized. |
