摘　　要：制备一种高收率、高效、环保的长链双季铵盐杀菌剂。以十二胺、环氧氯丙烷及N,N-二甲基-1,3-二氨基丙烷为原料,制备长链双季铵盐杀菌剂SX-28,并探讨其杀菌性能。研究表明,在同等投加量条件下,该杀菌剂对异养菌(TGB)、硫酸盐还原菌(SRB)和铁细菌(FB)的杀灭效果均优于1227及普通双季铵盐等常规杀菌剂,且其杀菌持续时间长。该杀菌剂在工业循环水中应用效果良好。A long-chain double quaternary ammonium salt bactericide with high yield,high efficiency and environmental protection was prepared.With dodecylamine,epichlorohydrin and N,N-dimethyl-1,3-diaminopropane as raw materials,a long chain bactericide of bisquaternary ammonium salt SX-28 was prepared,and the bactericidal capacity was discussed.The results indicate that this bactericide has excellent germicidal effect on TGB,FB and SRB in industrial circulating cooling water.Its bactericidal capacity is better than 1227 and normal bisquaternary ammonium salt.
