Abstract: With the potassium persulfate-sodium bisulfite as initiator,the copolymer(AB)was synthesized with sodium benzoate of p-acrylamide and Mannich base as monomers. The optimal synthesis conditions were determined as reaction between A and B with a molar ratio of 1.3 for 6.5 h at 80℃ using resource surface methodology. The inhibition performance of a novel copolymer(AB)for A3 steel in 20%HCl solution was investigated using polarization curves、AFM and XPS. The oil removal performances of copolymer(AB)were also investigated. The results showed that the inhibition rate was of 98.9%,with dosage of corrosion inhibitor 0.9% at 50℃,which was a mixed corrosion inhibitor mainly by restraining the anodic process. The oil removal rate of copolymer(AB) was 90.3%,under the conditions of 50 mg/L copolymer dosage,60℃ and pH=5.

Key words: Mannich base, sodium benzoate of p-acrylamide, aqueous solution radical copolymerization, corrosion inhibitor performance, oil removal

摘要: 以自制曼尼希碱(A)和对丙烯酰胺苯甲酸钠(B)为单体原料,以过硫酸钾和亚硫酸氢钠为复合引发剂,采用水溶液自由基聚合法制得聚合物(AB);利用响应面法优化合成工艺条件,确定其最佳工艺条件为n(曼尼希碱A):n(对丙烯酰胺苯甲酸钠B)为1.3:1,聚合时间为6.5h及聚合温度为80℃。采用Tafel极化曲线、AFM、XPS对该聚合物的缓蚀性能进行了研究,同时考察了该聚合物对油田废水的除油效果。结果表明:在50℃,聚合物的投加量为0.9%时,A3钢在20%的盐酸溶液中缓蚀剂率达到98.9%,且该聚合物为抑制阳极为主的缓蚀剂;当聚合物加入量为50mg/L、温度60℃、pH=5时,除油率达到90.3%。
