Clean production process of parachlorophenol

The invention provides a clean production process of parachlorophenol, which belongs to the technical field of organic synthesis and comprises the following steps: preparing parachlorophenol with high selectivity by using phenol, hydrogen peroxide and hydrochloric acid as raw materials and using a catalytic amount of tetradentate amine zinc imine as a catalyst under normal pressure; the tetradentate amine zinc imine has relatively large steric hindrance and electron cloud regulation and control capability, so that the insertion trend and activity of chlorine atoms can be effectively controlled, and the selectivity is remarkably improved; hydrogen peroxide and concentrated hydrochloric acid are used for in-situ preparation of chlorine, hydrogen peroxide is clean and environment-friendly, hydrochloric acid is cheap and easy to obtain and can be used as a reaction reagent and a reaction solvent, a byproduct is only water, the experimental process is clean and mild, and the method belongs to the technical field o
