Abstract: Firstly,sodium alkoxide was prepared by fatty alcohol ethoxylate and metal sodium,and polyethoxy glyceride was formed by sodium alkoxide and epoxy chloropropane.Then the tri-quaternary ammonium salt was obtained by the reaction of polyethoxy glyceride with pentamethyldiethylenetriamine under acidic condition.Structure of the product was characterized by infrared spectroscopy (IR),and its properties such as solubility,critical micelle concentration,surface tension and foam performance were measured.The results showed:the tri-quaternary ammonium salt has good solubility and high surface activity.Temperature has no virtual effect on its foaming properties and foaming stability.Condition pH has no big influence on foaming properties of the product,but its foaming stability is rather influenced by pH.The product shows good stability in hard water.

Key words: tri-quaternary ammonium salt cationic surfactant, synthesis, solubility, surface properties
