Abstract
The present invention relates to the technical field of peroxide decomposition, and discloses a method for preparing phenol, which comprises the following steps: (1) mixing cumene hydroperoxide and liquid acid or solid acid with a solvent to form a homogeneous solution or uniformly dispersed system; (2) loading the homogeneous solution or uniformly dispersed system of cumene hydroperoxide with a homogeneous solution or uniformly dispersed system of acid into a preheating module and preheating in a micro-channel continuous flow mode, preliminarily mixing the preheated materials for reaction in a mixing module in a micro-channel continuous flow mode, and then further mixing the materials for reaction in a series of mixing and reaction module groups in a micro-channel continuous flow mode, to obtain phenol. The method provided in the present invention is easy, simple and safe to operate, can implement continuous production of phenol product at a high yield ratio; in addition, since the reaction in the present invention is a cracking reaction, which releases heat strongly, the safety factor of the process is significantly improved owing to the strong heat release characteristic in conjunction with the unique heat transfer property of the micro-channels. With the method provided in the present invention, the yield of the product is higher than 99%.
