摘　　要：用卤代烃和硫脲合成了Ｓ－ 十六烷基异硫脲盐酸盐和Ｓ－ 苄基异硫脲盐酸盐，通过元素分析、红外光谱等确定了其组成和结构。以它们的乙醇溶液为固定相，以不同浓度的盐酸溶液为展开剂，用反相纸层析法对１１ 种稀土离子的萃取行为进行了研究，并对Ｌａ－ Ｔｂ，Ｅｕ－ Ｐｒ 等１２ 组稀土离子进行了纸上层析分离。S-Hexadecyl isothiourea hydrochloride and S-benzyl isothiourea hydrochloride have been synthesized by hylohydrocarbons and thiourea. The elemental composition and the structural charateristics were detemined by elemental analysis and IR. Two S-alkyl isothiourea hydrochlorides dissovlved partly in ethanol were used as stationary phase, hydrochloric acid solutions of different concertrations were used as the developer. Extraction power of two S-alkyl isothiourea hydrochlorides for 11 rare earth ions was studied in reversed paper chromatography, and they can be used by reversed paper chromatography to separate rare earth ions in mixtures, such as La-Tb, Eu-Pr and some other rare earth couple.
