Abstract: A Series of quaternary ammonium Gemini surfactants,8-3(OH)-8,8-3(OH)-12,8-3(OH)-16,12-3(OH)-12 and 16-3(OH)-16 were synthesized using epoxy chloropropane and various alkyl tertiary amines as starting materials.Surface activity,forming performance at various pH conditions,and emulsifying properties were investigated.The critical micelle concentration (cmc) of the five kinds of surfactant are 12.3×10-5,15.5×10-5,6.8×10-5,2.9×10-5 and 1.2×10-5 mol/L respectively,and their equilibrium surface tension (γcmc) are 46.04,37.20,39.61,39.34 and 38.12 mN/m respectively.The surfactant 8-3(OH)-12 displays outstanding foaming and emulsifying properties in both neutral and acidic condition (pH=2).The foam performance and emulsifying property of these Gemini surfactants could be promoted greatly under acidic condition.

Key words: Gemini surfactant, quaternary ammonium salt, performance
