摘要
以环氧氯丙烷、二癸基二甲基氯化铵（DDAC10）、甲硝唑、醋酸及盐酸为原料合成了一种硝基咪唑啉改性双链季铵盐，并测试了目标产物的红外光谱。采用绝迹稀释法评价了其对SRB的杀菌能力，以市面常见的1227和戊二醛做对比。结果表明，该硝基咪唑啉改性双链季铵盐具有优良的杀菌性能，在SRB菌量为103~106个/ml时，最低杀菌浓度可达40mg/L,在同等菌量的条件下，其对SRB的杀菌能力明显优于1227及戊二醛，同时对含有3%NaCl的饱和CO2的油田模拟水具有一定的缓蚀效果。
A nitroimidazoline modified double chain quaternary ammonium salt is synthetized by epichlorogydrin, didecyl dimethyl ammonium chloride（DDAC）, methonidazole, acetic acid and hydrochloric acid which named HGY-BA1, and the infrared spectroscopy of the product was evaluated. The bactericidal efficiency on sulfate reducing bacterial （SRB） and corrosion effect are tested. The experiment result indicates that HGY-BA1 can reach 40mg/l which is better than 1227 and glutaraldehyde when the amount of SRB is between 103～106 cell/ml. The product also showed a inhibition on carbon steel when exposed to the simulated oilfield water containing 3% NaCl and CO2 saturated solution.
