摘　　要：以系列直链/支链脂肪醇醚、氢氧化钠和氧气为原料,在自制的Pd/C多组分催化剂催化下,合成了系列脂肪醇醚羧酸盐阴离子表面活性剂,反应过程为一步氧化法。该工艺属高效原子经济性反应,反应条件温和,反应过程不采用有毒有害原料,不产生三废排放,符合绿色与可持续化发展的趋势。同时对系列产品的表面张力、泡沫性、润湿性、乳化性以及复配性等应用性能进行了研究,为其开拓更广阔的应用领域提供参考依据。Series of anionic surfactants alcohol ether carboxylates were synthesized from alcohol ethoxylates, sodium hydroxide and oxygen under the catalyzation of self-made Pd/C based multi-component catalyst. The one step oxidation synthesis was the most convenient and atom-economic method. The process was green and sustainable without toxic and hazardous materials and waste emissions. Such properties as surface tensions, foaming powers, wetting properties, emulsifing powers and compounding properties were tested. The results were helpful to expand more applications.
