Recently, there has been considerably interested in the development to new functional gemini type anionic surfactant, sodium bis-n-alkyl sulfonatosuccinate, had been synthesized through the addition reaction of sodium bisulfite to bis-n-alkyl maleate, in which water was azeotropically distilled by adding benzene to the reaction system, gave a good yield. All the surface activities including krafft point, surface tension, emulsion power and foaming were measure and cmc was evaluated in dilute solution. This results showed a lower ability in $27{sim}30dyne/cm$ than single-chain surfactant with $32{sim}35dyne/cm$ to surface tension. Also its cmc value much smaller in $(6.5{sim}10){ imes}10^{-4}mca{ell}/{ell}$ than single-chain surfactant with $(40{sim}45){ imes}10^{-4}mca{ell}/{ell}$ concentration. In foaming ability and foam stability of gemini surfactant had especially a good ability in approximately $100{sim}150ml$, and in emulsing power they exhibited a good emulsing phase and stability, and Krafft points were $0{sim}10^{circ}C$.
