| titleOfInvention | A kind of preparation method of p-diacetylbenzene |
| abstract | The invention provides a method for preparing paradiacetylbenzene, which uses paradiethylbenzene as a raw material, air as an oxidant, and one or both of cobalt naphthenate and manganese naphthenate as a catalyst to prepare paradiethylbenzene Acetophenone. The oxidant used in the method of the present invention is air, which is cheap and easy to obtain, and a large amount of nitrogen remaining after the reaction is used as a part of the tail gas, which can quickly remove the reaction heat, so as to easily realize continuous production with low energy consumption; the present invention does not use a solvent, so that the reaction The product is easy to separate; the catalyst adopted in the present invention has the advantages of simple structure, low dosage and high activity, and shortens the reaction time; the above advantages make the preparation method of p-diacetylbenzene of the present invention have broad industrial application prospects. |
