N,N′-bis[2-(dimethylamino)ethyl] terephthalamide was synthesized with N,N′-dimethyl-1,2-di-amine and 1,4-benzenedicarbonyl chloride which was prepared by terephthalic acid and thionyl chloride. Then three quaternary ammonium cationic Gemini surfactants were quaternized respectively with three bromododec-ane with different carbon chain length. The products structure was characterized by 1HNMR and IR. The re-sults of surface tension measurement indicated that the Gemini surfactants display higher surface activities. The minimum surface tension of the Gemini surfactants was near 29.85 mN/m. The results of the emulsifica-tion performance test indicated that emulsion stability time of quaternary ammonium Gemini surfactants to ker-osene/water system increased with the length of hydrophobic group increasing.
