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、1.90×10-4mol/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2.03×10-3mol/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。
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 and1 H NMR,and their surface activities were investigated and analyzed. The results showed the CMC andγcmcvalues 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^-3mol /L,respectively. The γcmcvalues 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.
