A novel of Gemini Anionic Surfactants with Di-Sulfonate was conveniently prepared by reactions of diglycidyl ether with long-chain fatty alcohols,and followed by reactions with chlorosulfonic acid.Bis- sulfonate were obtained by neutralization of the free acid with sodium hydroxide.The purity of the compounds were confirmed by thin-layer chromatography(TLC).It was proved that BF3-ether is more effective,re- action temperature 100℃ and reaction time 5h,diglycidyl/alcohol/cat=1/2.05/0.2(mol) The sulfate types...
