摘　　要：以对叔丁基苯酚、甲醛为主要原料合成杯芳烃母体对叔丁基杯[n]芳烃(n=4,6,8);以1,3-丙烷磺内酯、1,4-丁烷磺内酯为醚化试剂,经Williamson醚化反应,合成出6种杯芳烃基低聚表面活性剂。利用IR表征了中间体和最终产物的结构,确定了化合物的结构与所设计的分子结构相同。用染料法对所合成产物进行了定性鉴定,并用滴体积法测定了表面活性剂水溶液25℃时的表面张力。结果表明,随着杯芳烃空腔的逐渐增大,cmc值降低,γcmc值升高,Γcmc值下降,Am值升高。The p-ten-butyl calix[ n ] arene （ n = 4,6,8 ） were synthesized by p-ten-butyl phenol, formaldehyde aqueous solution as raw materials. Six kinds of calixarene oligomeric surfactants were prepared by etherification of the calix[ n] arene with 1,3-propane sultone and 1,4-butane sultone. The structures of intermediates and the final products were characterized by IR, and the structure of compound is similar with the structure of designed product. The products were qualitatively identified by dye method. The surface tensions of dilute aqueous solutions of the surfactants were measured at 25 ℃ by drop-volume method. The results indicate that with the calixarene cavity increases cmc and Гcmc of the surfactants solution decreases,but γcmc and Am increases.
