摘　　要：通过大规模工业化的方法来制备新型阴离子磺酸型双子表面活性剂DTM-12,该合成方法简单、反应条件温和、无需中间体的提纯,能够在可以接受的成本下进行大规模生产。对目标产物进行表征,对其表面活性进行测试,并将实验室制备、小试放大、中试生产的DTM-12各数据进行对比。结果表明,大规模制备的DTM-12分子结构与实验室制备的相同;其表面活性与实验室制备的相近,且均优于常用的传统表面活性剂。An anionic Gemini surfactant DTM- 12 was synthesized by largemild- scale synthesis process which pos- sessed the advantages such as easy method, low cost of reagents, and no intermediate. IR and 1H NMR spectra and the CMC data of DTM -12 from both laboratory and pilot production were characterized and compared. The results indicated that DTM - 12 from both cases and pilot production were the same in the molecule structure. Moreover, their surface activities were similar and superior to the traditional corresponding surfactants.
