Catalyst composition for producing catechol and hydroquinone and method for producing catechol and hydroquinone using the catalyst composition

摘要

The present invention relates to a catalyst composition for producing catechol and hydroquinone by selectively oxidizing phenol to 0.9 position with hydrogen peroxide as an oxidizing agent, and a method for preparing catechol and hydroquinone using the catalyst composition.;Existing catalyst is a homogeneous catalyst, it is difficult to recover the catalyst after the reaction, and the amount of waste water is generated, but the catalyst of the present invention is a heterogeneous catalyst, the recovery of the catalyst after the reaction is simple, and the waste water is generated almost directly because it is directly added to the distillation apparatus after the reaction. In addition, the production rate of catechol in the reaction product is high and has excellent activity.
