新型杀菌剂双季铵盐BQAS性能试验研究

Experimental Study on Performance of Bisquaternary Ammonium Salt

新型杀菌剂双季铵盐以其低毒、性能优良而受到广泛的关注。以自制的N,N-二甲基十二烷基叔胺和1,4-二溴丁烷为原料合成产物双季铵盐(BQAS)。对双季铵盐BQAS的杀菌性能及缓蚀性能研究表明,双季铵盐对SRB和TGB的杀灭能力均优于1227,双季铵盐在有氧中性水介质中表现出一定的缓蚀性能,并具有较强的杀菌能力,是一种吸附成膜型缓蚀剂。

The N, N-dimethyl dodecylamine and 1,4-dibromobutane were taken as the raw material to synthesize the bisquaternary ammonium salt (BQAS). The sterilizing performance and corrosion inhibiting performance of bisquaternary ammonium salt were compared with the performance of 1227. The result shows that the sterilizing and corrosion inhibiting performances of BQAS are better than the performances of 1227. The sterilizing and corrosion inhibiting mechanisms of bisquaternary ammonium salt are introduced.
