Abstract: 1,3-Di-quinolin-6-yl-urea was synthesized from 6-aminoquinoline and triphosgene in the
presence of a catalytic amount of triethylamine, and then it reacted respectively with three bromoalkanes to
produce three bis-quinolineaternary ammonium bromides, novel Gemini surfactants. Their structures were

confirmed by FTIR, HNMR, CNMR and ESI-MS. The synthesis conditions of the intermediate and the
target quinoline Gemini surfactant were optimized. The optimum reaction conditions for the intermediate
were obtained as follows: methylene chloride as reaction solvent, molar ratio of 6-aminoquinoline to
triphosgene 5∶1, reaction time 6 h. Under these conditions, the yield of the intermediate, 1,3-di-
quinolin-6-yl-urea was up to 88%. Under the optimum conditions of N,N-dimethylformamide (DMF) as
solvent, reaction temperature 110 ℃, reaction time 8 h, mole ratio of intermediate to 1-bromododecane 1∶
14, the yield of target compound reached 74%. The interfacial tensions of the Gemini surfactants were
measured in chloroform-water system. The results showed that the diffusion of quinoline Gemini
surfactants from chloroform solution into the chloroform-water interface was controlled by pure diffusion
adsorption.
