摘要： 脱氢枞胺经N-烷基化反应合成N，N'-二脱氢枞基-α，ω-丙二胺，再与溴代聚乙二醇单甲醚经N-烷基化反应制备了4种不同分子质量的N，N'-二聚乙二醇单甲醚-N，N'-二脱氢枞基-α，ω-丙二胺松香基聚氧乙烯胺型双子表面活性剂RPG550、RPG1000、RPG2000和RPG5000。通过FT-IR和 1H NMR 对产物进行了结构表征，并对其临界胶束浓度（CMC）及其表面张力（γcmc）、对松节油/水体系或液体石蜡/水体系的乳化能力、抑泡及消泡能力进行了研究。研究结果表明：RPG550、RPG1000、RPG2000、RPG5000的CMC值分别为1.00×10-3、9.75×10-4、5.25×10-4、1.90×10-4 mol/L，γcmc值分别为26.4、27.5、22.8、22.2 mN/m，都低于市售表面活性剂壬基酚聚氧乙烯醚TX-10的相应值（CMC值2.03×10-3 mol/L，γcmc值31.6 mN/m）；其对松节油/水体系以及液体石蜡/水体系有较好的乳化能力，并有明显的抑泡能力和一定的消泡能力，抑泡能力明显好于TX-10。

Abstract: Four rosin-based polyoxyethylene amine gemini surfactants N,N'-methoxypolyethylene glycols-N,N'-dehydroabietylamine-α,ω-promethylene diamine (RPG550, RPG1000, RPG2000, and RPG5000) with different molecular weights, were synthesized from dehydroabietylamine through N-alkylation reactions. The structures of these compounds were confirmed by FT-IR and 1H NMR, and their surface activities were investigated and analyzed. The results showed the CMC and γcmc values of these four compounds were lower than that of commercial TX-10. The CMC values of RPG550, RPG1000, RPG2000, RPG5000 and TX-10 were 1.00×10-3, 9.75×10-4, 5.25×10-4, 1.90×10-4, and 2.03×10-3 mol/L, respectively. The γcmc values of these surfactants were 26.4, 27.5, 22.8, 22.2, and 31.6 mN/m, respectively. These compounds have excellent emulsifiability in the turpentine/water system and the liquid paraffin/water system. They also have good foam inhibition and defoaming power properties, and the foam inhibition property of RPG is significantly better than that of TX-10.
