, -diallyl- , , -tripropylhexane-1,6-diaminium chloride (NDTHDC) and its polymer poly( , -diallyl- , , -tripropylhexane-1,6-diaminium chloride) (poly-NDTHDC) were synthesized and tested against API X60 carbon steel corrosion in 15 wt % HCl solution. Weight loss, electrochemical, and surface analysis techniques were used. Results show that poly-NDTHDC is better than NDTHDC. Moreover, 1000 mg/L NDTHDC protected the studied surface by 79.1% at 25 °C, while 100 mg/L poly-NDTHDC afforded 86.1% protection. Inhibition efficiency increases with temperature (up to 60 °C) but depreciates thereafter. NDTHDC and poly-NDTHDC perform better under the hydrodynamic condition than the static condition. TGA and FTIR results reveal that poly-NDTHDC is chemically and thermally stable.
合成了二烯丙基三丙基己烷-1,6-二氯化铵（NDTHDC）及其聚合物聚（二烯丙基三丙基己烷-1,6-二氯化铵）（聚-NDTHDC），并在15 wt%盐酸溶液中对API X60碳钢腐蚀进行了测试。采用了失重法、电化学法和表面分析法。结果表明，聚-NDTHDC比NDTHDC更好。此外，1000 mg/L的NDTHDC在25℃时对研究表面的保护率为79.1%，而100 mg/L的聚-NDTHDC提供了86.1%的保护率。缓蚀效率随温度升高（直至60℃）而增加，但此后降低。NDTHDC和聚-NDTHDC在流体动力学条件下比静态条件下表现更好。热重分析（TGA）和傅里叶变换红外光谱（FTIR）结果表明，聚-NDTHDC具有化学和热稳定性。
