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。
以環氧氯丙烷、二癸基二甲基氯化銨(DDAC10)、甲硝唑、醋痠及鹽痠為原料閤成瞭一種硝基咪唑啉改性雙鏈季銨鹽,併測試瞭目標產物的紅外光譜。採用絕跡稀釋法評價瞭其對SRB的殺菌能力,以市麵常見的1227和戊二醛做對比。結果錶明,該硝基咪唑啉改性雙鏈季銨鹽具有優良的殺菌性能,在SRB菌量為103~106箇/ml時,最低殺菌濃度可達40mg/L,在同等菌量的條件下,其對SRB的殺菌能力明顯優于1227及戊二醛,同時對含有3%NaCl的飽和CO2的油田模擬水具有一定的緩蝕效果。

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.
