The invention discloses a circulating cooling water bactericide and a synthesis method thereof. The synthesis method comprises the following steps: mixing N,N-dimethylbenzylamine and a solvent uniformly, heating to 70-90° C. under stirring conditions, adding hydrochloric acid , stir for 20-30 min, continue stirring and add epichlorohydrin within 30 min, continue to react for 9-11 h under stirring condition, stop heating and lower to room temperature 20-25 ℃ to obtain a crude product; put the obtained crude product at 70 Rotary evaporation under reduced pressure at ~90° C. until all the solvent is evaporated to dryness to obtain the circulating cooling water bactericide. The synthesis method of the invention has mild reaction conditions and wide application range of substrates; the circulating cooling water bactericide has less dosage, short bactericidal action time and high bactericidal efficiency. |
