Method for preparing diphenyl ketone from diphenylmethane

The invention discloses a method for preparing diphenyl ketone from diphenylmethane, and belongs to the technical field of organic synthesis. According to the method, in a solvent system, peroxide is used as an oxidizing agent, nitrogen-doped carbon nanotubes are used as a catalyst, oxidation reaction of diphenylmethane is carried out, and diphenylketone is obtained. According to the invention, the peroxide tert-butyl hydroperoxide is used as the oxidant, and the reaction is carried out under normal pressure, so that the reaction safety is effectively improved, and the operation difficulty of the reaction is reduced. According to the method, the yield is remarkably improved by regulating and controlling the nitrogen content and dosage of the catalyst nitrogen-doped carbon nanotube. 本发明公开了一种二苯基甲烷制备二苯基甲酮的方法，属于有机合成技术领域；本发明通过在溶剂体系中，以过氧化物为氧化剂，以氮掺杂碳纳米管为催化剂，进行二苯基甲烷的氧化反应，得到二苯基甲酮。本发明以过氧化物叔丁基过氧化氢为氧化剂，在常压下进行反应，有效的提高了反应的安全性及降低了反应的操作难度。本发明通过调控催化剂氮掺杂碳纳米管的氮含量和用量，显著提升产率。
