硫醚既是有机合成的原料,又是很好的溶剂和萃取剂,用来提取稀有金属和贵金属。据报道,硫醚的合成方法大致有下列几种: ①硫化钠和卤代烃作用 Na_2S+2RXR-S-R+2NaX ②格利雅试剂和二甲亚基砜作用 RMgX+Me_2SoRCH_2SMe+Mg(OH)X ③硫脲盐和卤代烃反应 R~1SNa+R~2XR~1-S-R~2+NaX Thioether is both organic synthesis of raw materials, but also a good solvent and extractant, used to extract rare metals and precious metals. It has been reported that the synthetic methods of thioether generally have the following: ① sodium sulfide and halogenated hydrocarbon effect of Na_2S + 2RXR-S-R + 2NaX ② Grignard reagent and dimethyl sulfone effect of RMgX + Me_2SoRCH_2SMe + Mg (OH) X ③ thiourea salt and halogenated hydrocarbons reaction R ~ 1SNa + R ~ 2XR ~ 1-SR ~ 2 + NaX
