Double alkyl quaternary ammonium salts have been prep ared through bromoalkane, an intermediate material. In the ammonifying procedure, al cohol is used as solvent or phase transfer catalyst is added. The results sh ow that the reaction time decreases evidently and the yield of bactericide in creases further. The bactericidal performance of the products has been evalu ated and compared with the bactericide of 1227. The double-octyl quaternary ammonium bromide is an ideal bactericide and the killing ratio to the SRB and TGB reache s 100% in a lower concentration (30 mg/L). It gives better bactericidal performa nce than 1227.
