Method of synthesizing cation bleaching activating agent

The invention discloses a method of synthesizing a cation bleaching activating agent and belongs to the technical field of fine chemical engineering. The method disclosed by the invention comprises the following steps: dissolving 4-chloromethyl benzoyl chloride and caprolactam into a solvent; adding an acid binding agent into a caprolactam solution to be dissolved; gradually dropping a 4-chloromethyl benzoyl chloride solution into a caprolactam-acid binding agent solution to be mixed by stirring; finally, adding tertiary amine to react and drying the solvent by spinning after the reaction is finished; washing an obtained solid to obtain a target product. According to the method disclosed by the invention, a synthesis process of the cation bleaching activating agent is greatly simplified; conditions needed for synthesizing the cation bleaching activating agent are reduced; meanwhile, the higher yield is guaranteed and the method is applicable to industrial popularization.
