Abstract: A new adsorptive resin, N,Ndi(2chloroethyl)sulfonamide resin, was synthesized through the modification of sulfuric acid resin with di(2chloroethyl)amine. Its capacity and selectivity on the adsorption of six typical organic sulfides was investigated in the hydrocarbon samples. The results indicated that the resin exhibits different adsorption abilities for various sulfides; the adsorption activity decrease in the order of primary mercaptan, secondary thiophene mercaptan, and then sulfur ethers benzothiophene.
