Novel sodium 2-2-(alkylaryloxy-alkylamidoethanesulfonates (m+nAr-T, m, n: carbon numbers; Ar: aromatic nucleus; T: taurine) with high purity were synthesized through bromization, esterification, Fries rearrangement, Pd-catalyzed hydrogenation, Williamson reaction, and acylation, et al, using carboxylic acid, phenol and taurine as starting materials. The structures and purities were characterized.
