Two bactericides, N-phenylmaleimide(NPMI) and N-benzylmaleimide(NBMI), are prepared.Their sterilizing performance for cooling water used in petrochemical plants has been evaluated via a static sterilizing experiment regarding three kinds of main bacteria involved in wastewater of petrochemical plants, i.e.heterotroph bacteria, iron bacteria and sulfate-reducing bacteria, and compared with commonly used bactericides isothiazolinone and "1227" (dodecyl dimethyl benzyl ammonium chloride).It is shown that NBMI is a highly efficient bactericide, its overall performance is superior to isothiazolinone.In comparison with "1227", its sterilizing efficiency after 1 h is a little bit lower than "1227", while its 24 h long term effect is much better than "1227".NPMI has some sterilizing effect on heterotroph bacteria and iron bacteria, while it has no effect on sulfate-reducing bacteria.
