摘　　要：实验室合成了一种新型的双子表面活性剂,记作PR—J。用红外光谱对产物进行了定性分析并用元素分析仪对产物中的各种元素进行了定量分析。结果表明合成的产物就是目标产物。对PR—J的性能进行了详细的讨论。PR—J的临界胶束浓度cmc=7.27×10^(-4),对应的表面张力γ_(cmc)=39.55 mN/m。实验还测定了PR—J的乳化能力、增溶能力、发泡性和稳泡性,发现PR—J的上述性能优于常用的十二烷基苯磺酸钠(LDS),但发泡性和稳泡性不及十八烷基羧酸钠(TCN)。An cationi gemini surfactant denoted PR--J was synthesized in lab. The product was characterized by the methods of IR for qualitative analysis and elemental analyzer for quantitative analysis of the various elements in the product. The results showed that the synthetic product was the target product. And the interfacial properties of PR--J has been discussed. The cmc of PR--J is 7.27 ~ 10-4 mol,/L and the corresponding surface tension：ymax = 39.5 mN/m. The emulsifying capacity, solubilizing capacity, foam ability and foam stabilizer were character- ized. It found that the performance of the PR--] were better than the commonly used sodium dodeeyl benzene sul- fonate （LDS）, but the foam ability and foam stability were less than octadecyl sodium carboxylates （TCN）.
