Preparation method of monochlorinated phenol compound

The invention discloses a preparation method of a monochlorinated phenol compound, and belongs to the technical field of compound synthesis, a phenol compound is used as a raw material, hydrochloric acid is used as a chlorine source and a solvent, copper chloride is used as a catalyst, the oxygen content in a system is regulated and controlled through a ceramic microporous membrane, oxidation reaction and chlorination reaction are carried out at the same time under mild conditions, and the monochlorinated phenol compound is obtained. And the selectivity of monochlorinated products is high. The hydrochloric acid is consumed and can be repeatedly used, and the problem that a large amount of industrial byproduct hydrochloric acid is difficult to treat can be solved; copper chloride only needs a catalytic amount, so that the use of heavy metals is remarkably reduced; the method is mild in condition, controllable in operation and easy to industrialize. 本发明公开了一种单氯代苯酚类化合物的制备方法，属于化合物合成技术领域，以苯酚类化合物为原料，盐酸作为氯源和溶剂，氯化铜为催化
