The sodium decyldiphenylether disulfonate was synthesized by diphenyl ether, bromodecane and chloric sulfoacid. The synthetic conditions of alkylation and sulfonation were investigated. Alkylation was carried out with n(diphenyl ether) : n(bromodecane)=1: 1 and n(diphenyl ether) : n(catalysis)=4 :1 at 75 ℃ for 5 h to attain 87.62 % yield. Sulfonation with n(alkylated diphenyl ether) : n(chloric sulfoacid)=1 : 4 was carried out at 15 ℃ for 20 rain, and the number of sulfonic acid group per molecule was 1.91.
