【摘要】 主要介绍了N-酰基ED3A螯合性表面活性剂的表面活性、泡沫稳定性、螯合能力、洗涤能力、润湿能力等性能,认为当烷链长度在12~18时,该类表面活性剂同时具备优异的表面活性和螯合性,泡沫稳定性好,尤其在电解质存在下。但该类表面活性剂的表面活性等性能与体系pH有一定的相关性,其螯合能力与表面活性剂的浓度也有相关性。更多还原

【Abstract】 Performances of chelating surfactant,such as surface activity,foam stability,chelating capacity,detergency and wetting power et al were presented.When the carbon chain length of the chelating surfactant is within the range of 12～18 C,it has excellent surface activity and chelating capacity as well as good foam stability,especially with the existence of electrolytes.There is certain correlation between the surface activity of this kind of surfactant and the pH value of the system,and there is correlation between the chelating capacity and the concentration of the surfactant solution.更多还原
