Abstract：The intermediate, amide compound（3）, was prepared by Williamson reaction， oxidation， chloroformylation and amidation， using salicylaldehyde and 1,2-dibromoethane as materials. The novel biphenyl type quaternary ammonium gemini surfactant(4) was synthesized by quaternization of 3 with1-bromodecane. The structure was characterized by 1H NMR and IR． The surface activities of 4 were investigated. The results showed that 4 had good acid and salt resistance. In 0.1 mol·L-1 NaCl solution, the γ was 36.8 mN·m-1, the CMC was 0.20 mmol·L-1. In HCl(pH=1), the γ was 32.5 mN·m-1, the CMC was 0.16 mmol·L-1.
