| titleOfInvention | Preparation method of p-anisidine and equipment for preparing p-anisidine |
| abstract | The invention provides a preparation method of p-anisidine and equipment for preparing the p-anisidine. The preparation method comprises the following steps: step 1) providing a p-nitroanisole raw material, and carrying out hot melting treatment on the p-nitroanisole raw material to obtain p-nitroanisole in a molten state; step 2) under the condition that a catalyst exists, taking a first part of p-nitroanisole in a molten state to carry out hydrogenation reaction to obtain a p-anisidine primary product; and 3) continuously adding a second part of p-nitroanisole in a molten state into the p-anisidine primary product, supplementing a catalyst, continuously carrying out hydrogenation reaction, and separating and obtaining a p-anisidine final product. The preparation method of the p-anisidine is simple and easy, can save the cost of raw materials, does not need to use other organic solvents, does not need to recover the solvents, can save the cost of the raw materials, does not generate high-salt high-COD wastewater, is green and environment-friendly, and does not cause pollution to the environment. |
