Synthesis and evaluation of Anionic Gemini surfactant

Take the lauric acid, the ethylene diamine, the chloroacetic acid, the soda ash as raw material synthesized a new type of Anionic Gemini surfactants-N, N'-double lauroyl ethylene diamine two sodium acetate, The properties of the product were characterized, and the physical and chemical properties were determined. The experimental results can be seen that the anionic Gemini surfactants can greatly reduce the oil/water interface tension, and it has good viscosity properties, Thus deduced that the Gemini surfactants is better than the ordinary surfactant better table (world) surface activity, Can be used in the tertiary oil recovery field.
