Preparation, Surface Activity and Application of Fluoro-Spreading Agent

Abstract:

Ammonium perfluoro-2,5-bis (trifluoromethyl)-3,6-dioxopelargonate (FY1) was synthesized from perfluoro-2,5-bis (trifluoromethyl)-3,6-dioxopelargonic acid and ammonia in ether, and was characterized by IR and ¹H NMR. Its surface activity and spreading performance on gasoline were investigated in detail. The critical micelle concentration (CMC) of FY1 in aqueous solution was 0.25 g / L, and the surface tension at CMC (ڃ_cmc) was 17.25 mN / m. The aqueous solution of FY1 could spread on the surface of gasoline, but the aqueous solution of FY1 mixed with sodium dodecyl benzene sulfonate (SDBS), sodium dodecyl sulfate (SDS), n-octanol, 2-ethyl hexanol or VF respectively could not spread on gasoline. However, the aqueous solution of two or three components of FY1 with anion fluoro-surfactant Intechem-1 and SDS or n-octanol could spread on gasoline, and the biggest covering degree on gasoline reached 80.2% in 10min. It can decrease the volatilization of gasoline and can be employed to develop a new aqueous film-forming foam for oil-fire fighting.
