摘　　要：通过调整体系中酰胺基叔胺碳链比例,并引入乙二胺基乙磺酸钠和丙烯酸,成功合成了一种新型混合碳链氧化胺/磺酸盐复合表面活性剂(NY-surf)。对其结构进行了表征,研究了其表面活性、泡沫性能、乳化及润湿性能。结果表明,NY-surf具有良好的表面活性,临界表面张力只有29.67 mN/m,泡沫稳定性良好,在高温、高盐和高原油的环境下也具有卓越的耐受能力。乳状液静置120 min后的析水率仅为35%,同时具有润湿反转能力,能将原来油湿表面变为水湿表面。This paper presents the synthesis of a novel composite surfactant(NY-surf)comprising mixed carbon chain amine oxide and sulfonate.The carbon chain ratio of tertiary amide amine was adjusted,and ethylene diamine ethane sulfonate and acrylic acid were introduced to enhance its properties.The structural characterization revealed that NY-surf exhibited excellent surface activity with a value of 29.67 mN/m.Furthermore,it demonstrated good foam stability and remarkable resistance to high temperature,high salt,and high crude oil environments.Additionally,NY-surf displayed strong emulsification ability with only a 35%water extraction rate after standing for 120 min.
