Title: Synthesis and Interfacial Activity of Alkyl Sulfobetaine Type Surfactants
Abstract: Tetradecyl sulfobetaine(BE14)and hexadecyl sulfobetaine(BE16) were synthesized by one-step reaction,and the reducing oil/water interfacial tension properties of BE14 and BE16 were investigated in high salinity water.It was found that BE14 and BE16 were found to be compatible with high salinity water.oil/water interfacial tension was reduced to 10-2 mN/m magnitude for 0.011%-0.182%(mass fraction)BE14 and ultra-low interfacial tension was reached for 0.012%-0.078% BE16.Furthermore,it also exhibits ultra-low interfacial tension for the mixed systems of 0.039% BE16 and 800-2 500 mg/L HPAM.
