| titleOfInvention | Synthesis method of p-phenylenediame |
| abstract | The invention discloses a synthesis method of p-phenylenediame. The method comprises the following steps: placing magnetic Mg/Al-hydrotalcite solid base catalyst and p-nitroaniline in a reaction container, heating, slowly dropping hydrazine hydrate to react at 0-100 DEG C for 0.5-20h, filtrating the hot reaction solution after the reaction, cooling, standing to precipitate white crystals, then filtrating the postcrystalline reaction solution, and drying to obtain the finished product. The invention adopts magnetic solid base as catalyst, uses hydrazine hydrate to reduce the nitryl group, reduces the emission of three wastes in the reaction process, simplifies the technology, increases the yield and purity of the product and ensures that the synthesis technology is suitable for industrialization. |
