摘　　要：以十二烷基伯胺和四甲基脲为原料合成了十二烷基四甲基胍及其盐酸盐。后者再与环氧氯丙烷反应制备了十二烷基四甲基胍双子阳离子表面活性剂,通过IR和1HNMR鉴定了其结构,并考察了其性能。结果表明,十二烷基四甲基胍双子表面活性剂的临界胶束浓度(cm c)为2.5×10-4mol/L,cγm c为28.5 mN/m,其表面活性明显高于单十二烷基胍盐酸盐。最后以十二烷基四甲基胍双子表面活性剂为模板剂制备了纳米S iO2粒子。Alkyl tetramethyl guanidine and its hydrochloride salt were prepared from alkyl primary amine and tetramethyl urea as starting materials. The product further reacted with epichlorohydrin to prepare alkyl tetramethyl guanidine gemini surfactants. The structure of target product was identified by IR and ^1HNMR, and properties of target product were examined. Results showed that cmc and γcmc of alkyl tetramethyl gemini aurfactants were 2. 5 × 10^-4 mol/L and 28.5 mN/m respectively. The surface activity of the target product is aignificanfly higher than that of single alkyl tetramethyl guanidine. Nano SiO2 particulates were successfully prepared with the alkyl tetramethyl guanidine gemini surfactants as template.
