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.
