摘　　要：以咪唑和溴代十二烷为原料、1,2-二溴乙烷(1,4-二溴丁烷、对二溴苄)为联接基团,经两步反应合成标题化合物。利用IR、1HNMR对目标产物进行结构表征,并测定了目标产物的CMC、润湿性和泡沫稳定性。结果表明,合成的表面活性剂具有较低的CMC值,不同联接基团对CMC值影响不大,柔性联接基团的表面活性剂具有较好的润湿性和泡沫稳定性。Alkyl imidazole surfactants with different spacer were synthesized via two steps with imidazole,bromododecane and 1,2-dibromethane（ 1,4-dibromo-butane,dibromo-p-xylene） as raw material. The structures were confirmed by IR and1 HNMR. The CMC value,wettability and foam stability of the target products were tested. Results show that the synthesized of alkyl imidazole surfactants have low CMC values. The effect of different spacer on CMC values is not obvious. Alkyl imidazole surfactants with the flexible spacer have better wettability and foam stability.
