摘　　要：以α-十六烯、二苯醚在催化剂的作用下合成十六烷基二苯醚,再采用氨基磺酸作为磺化剂,尿素为助溶剂成功合成了十六烷基二苯醚双磺酸钠,对合成过程中烷基化与磺化反应的工艺条件进行了优化。烷基化的最佳反应条件为:n(α-十六烯):n(二苯醚)=1:1,反应温度为80℃,反应时间为6h,烷基化的产率可达85.42%。磺化的最佳反应条件为:n(烷基二苯醚):n(氨基磺酸)=1:4,反应温度为95℃,反应时间为2h,磺酸基数目为1.84。Hexadecyl diphenyl ether was synthesized by the alkylation reaction of alpha-hexadecene and diphenyl oxide.Furthermore,hexadecyl diphenyl ether disulfonate was obtained by the sulfonation of hexadecyl diphenyl ether with amino sulfonic acide as sulfonation agent and urea as cosolvent.The synthetic conditions of alkylation and sulfonation were optimized.From the experiment the optimal reaction conditions were found as： Alkylation was carried out with n（alpha-hexadecene）：n（diphenyl）=1：1 at 80℃ for 6 h to attain 85.42% yield.Sulfonation was with n（Hexadecyl diphenyl ether）：n（amino sulfonic acide）=1：4 at 95℃ for 2 h,and the number of sulfonic acid group per molecule was 1.84.
