- W2352672313 abstract "The modified bis-quaternary ammonium salt is successfully synthesized using epichlorohydrin (ECH),N,N-dimethyl dodecyl amine (DMA12),metronidazole (MDZ) and hydrochloride (HCl).The synthesis conditions are studied through orthogonal and single factor experiments,with the yield of modified bis-quaternary ammonium salt being as indicator.The bactericidal performance of the product is evaluated by dilution-to-extinction method.The experimental results show that the yield reaches to 78% in the conditions of the reaction temperature of 80 °C,the substance amount ratio of reactants n(ECH)∶n(DMA12)∶n(MDZ)∶n(HCl)of 0.5∶1∶1∶1 and the reaction time of 12 hours.The bactericidal rate of the product of the mass concentration is 20 mg/L to SRB and TG can reach to 100%.Its bactericidal effect is evidently better than that of 1227." @default.
