| description | The invention discloses a synthesis method of 5-bromine1-naphthol, and belongs to the technical field of organic synthesis. The method comprises the following steps: (1) dissolving 5-bromine-1-naphthylamine into acetic acid, adding sulfuric acid with the mass concentration of 70%-80%, adding a catalyst and reacting at 80-100 DEG C, wherein the catalyst is a metal oxide; and (2) after reaction is ended, cooling, and carrying out suction filtration to obtain a 5-bromine1-naphthol crude product. With the 5-bromine1-naphthol as a raw material, reaction is carried out at ordinary pressure in the presence of the catalyst, so that the method is relatively high in yield, high in maneuverability, relatively low in equipment cost, and wide in industrial popularization prospect. |
