Sodium oleyl sulfate with high double bond retention of 95.69 % (SOS-95) was successfully prepared by using sulfamic acid as a sulfating reagent, and its structure was identified by Fourier transform infrared (FT-IR) and hydrogen nuclear magnetic resonance spectroscopy (¹H NMR). Compared with octadecyl sodium sulfate (OSS) and sodium oleyl sulfate (SOS-77) with double bond retention rate of 77.38 %, the surface properties such as equilibrium surface tension, dynamic surface tension, and dynamic contact angle were analyzed. The results showed that SOS-95 had a lower surface tension (γ_cmc) of 31.96 mN/m, and the lower critical micelle concentration (CMC) of 0.028 mmol/L. Moreover, it had good adsorption, diffusion and relatively excellent spreading performances, the contact angle can reach as low as 56.87 ° in 130 s. The aggregation behavior was researched by transmission electron microscopy (TEM), and the sizes of the aggregates were analyzed by dynamic light scattering (DLS). The results showed that sphere-like micelles were formed spontaneously by aqueous solutions of SOS-95 at CMC, and the higher the concentration, the larger the size of the aggregates. Polarized optical microscopy (POM) combined with small Angle X-ray scattering (SAXS) analysis confirmed that lamellar phase liquid crystal structure with Maltese cross flower was formed in aqueous of SOS-95.

以氨基磺酸为硫酸化试剂成功制备了双键保留率高达95.69%的油基硫酸钠（SOS-95），并通过傅里叶变换红外（FT-IR）和氢核磁共振光谱对其结构进行了鉴定（¹核磁共振）。与双键保留率为77.38%的十八烷基硫酸钠（OSS）和油基硫酸钠（SOS-77）相比，分析了其平衡表面张力、动态表面张力和动态接触角等表面性质。结果表明，SOS-95具有较低的表面张力（γ _CMC) 为 31.96 mN/m，下临界胶束浓度 (CMC) 为 0.028 mmol/L。此外，它具有良好的吸附、扩散和较好的铺展性能，130 s内接触角可低至56.87°。通过透射电子显微镜 (TEM) 研究聚集行为，并通过动态光散射 (DLS) 分析聚集体的大小。结果表明，SOS-95的水溶液在CMC处自发形成球形胶束，浓度越高，聚集体的尺寸越大。偏光显微镜 (POM) 结合小角 X 射线散射 (SAXS) 分析证实，在 SOS-95 水溶液中形成了具有马耳他十字花的层状相液晶结构。
