Application of a method and a bath of synthetic cationic bleach activators

The present invention discloses a method and a bath application of synthetic cationic bleach activators TBLC, belonging to the field of chemical technology. The method of the present invention is to provide 4-chloromethyl-benzoyl chloride and caprolactam dissolved in a solvent, then an acid binding agent is added to the solution of caprolactam dissolved, then 4-chloromethyl benzoyl chloride was added dropwise to a solution of caprolactam - acid-binding agent mixed solution was stirred, and finally the tertiary amine is added to react rotary evaporation after the reaction, the desired product is obtained after the resultant solid was washed. The present invention provides a method greatly simplifies the synthesis of cationic bleach activators TBLC reduced synthetic cationic bleach activators TBLC conditions required, while ensuring a high yield, is adapted to promote the industrialization.
