Progress in Research of Alkyl Diphenyl Ether Disulfonate

The synthesis, production and application of the surfactant alkyl diphenyl ether disulfonate were reviewed. The research trends of the catalyst for Friedel-Crafts alkylation of diphenyl ether, and the progress in sulfonation and application of this kind of surfactant were emphatically expatiated. Lewis acid, supported AlCl3,super acidic catalyst, heteropolyacid and ion liquid were the catalysts commonly used for diphenyl ether alkylation. When the ion liquid catalyst prepared based on 1,3-alkylimidazole, alkyl quaternary ammonium salt and AlCl3 was used in synthesis of alkyl diphenyl ether, the reaction exhibited advantages of no environmental pollution and higher yield of product.
