| Abstract: | With p nonylphenol and formaldehyde as raw materials,bis (2 hydroxy 5 nonyl phenyl)methane was prepared at 80 ℃ with catalyst,and reacted with epichlorohydrin under alkaline condition to afford the intermediate SM.Then at 60 ℃ in isopropyl alcohol the intermediate SM reacted with triethanolamine hydrochloride to afford a gemini surfactant,structure of which was characterized by elementary analysis and IR.The total yield was 41.4%.Critical micelle concentration and surface tension of the gemini surfactant in aqueous solution were determined,i.e. cmc=0 04 mmol/L, γ cmc =20 4 mN/m. |
