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 conj…
