摘　　要：以油酸为原料,双氧水为氧化剂采用一锅法合成了9, 10-二羟基硬脂酸钠(SDHS),该合成方法效率高、污染小,产物结构经核磁与质谱表征,产物纯度经气相色谱和液相色谱确定。研究了SDHS在表面张力、乳化、泡沫、润湿、去污等方面的性能。结果表明,SDHS的纯度较高且表面活性较好,可以在低浓度下稳定O/W乳状液;SDHS是一类低泡型表面活性剂且泡沫稳定性较差;SDHS具有良好的润湿性能和较好的去污性能,适用于洗涤类产品配方中。Sodium 9,10-dihydroxystearate(SDHS) was synthesized from oleic acid and hydrogen peroxide. Compared with the traditional method for preparing SDHS, this synthetic method had the advantages of short reaction time, high efficiency, no waste water, and low environmental pollution. The product was characterized by 1 H-NMR, mass spectroscopy, GC and HPLC. The surface tension, detergency and the emulsifying, foaming and wetting properties of SDHS were studied. The results show that the SDHS synthesized by this method has higher purity;SDHS has good surface-active performance;the emulsifying ability of SDHS is better than those of sodium stearate and sodium oleate;it can stabilize O/W emulsions at low concentrations. Compared with traditional anionic surfactants, SDHS has poor foaming performance. SDHS is a kind of low-foaming surfactant and has poor foam stability. SDHS has good wetting performance, and its wetting power is better than sodium oleate and sodium stearate. The detergency experiment shows that SDHS has better cleaning performance, especially for sebum stained cloth. SDHS is suitable to be used in various detergent formulations.
