摘要: The invention discloses a perfluoro-hexyl sulphonyl oxygen benzyl amine oxide surface active agent as well asand preparation method and an application thereof. structural general formula of the is shown in 1 specification, wherein R1 R2 are -CH3, -CH2CH3 or -CH2CH2OH. comprises following steps of: applying sulfuryl fluoride fluorine-containing precursor material; carrying out sulfonic acid esterification with p-hydroxybenzylalcohol, chlorine substitution halogenated reagent, oxidaammoniationtion secondary amine, oxidation hydrogen peroxide so to obtain agent. has advantages no perfluoro-octyl group lasting organic pollutant characteristics, high activity low critical micelle concentration; aqueous film-forming foam fire-extinguishing obtained by compounding spreading speed excellent fire extinguishing property. Formula I.
