Abstract：A important intermediate of sulfonate amphoteric surfactant, sodium 3-chloro-2-hydroxy propanesulfate（2）， was synthesized by acidcatalyted ringopening reaction, using epichlorohydrin(1) and NaHSO3 as material, Na2SO3 as initiator， EDTA2 Na as complexing synergist． The structure was confirmed by 1H NMR, IR and ESI-MS. The yield of 2 was 81.55% under the optimum reaction conditions［1 0.55 mol, n(NaHSO3）: n（Na2SO3）: n（EDTA2Na）: n（H2O)=1.00 : 0.04 : 0.01 : 9.50， dropping time of 1 was 15 min, rotating speed is varied from 100 rpm to 300 rpm, at 70 ℃ for 1.25 h］.
