Synthesis and properties of mixed carbon chain oxidized amine/sulfonate composite surfactants
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 structur-al 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.
