  • 方法一:其制备方法有无水乙醇法、氯乙烷法、乙醇(乙烯)法等。 (1)无水乙醇法 以无水乙醇、发烟硫酸和硫氢化钠为原料制得。C 2 H 5 OH+H 2 SO 4 ·SO 3 →C 2 H 5 OSO 2 OH+H 2 SO 4 2C 2 H 5 OSO 2 OH+Na 2 CO 3 →2C 2 H 5 OSO 2 ONa+H 2 O+CO 2 ↑ C 2 H 5 OSO 2 ONa+NaSH→C 2 H 5 SH+Na 2 SO 4 此法是国内较成熟的生产工艺,缺点是路线较长,收率较低,对原料要求较高,酸、碱用量大,对设备腐蚀性强。 (2)氯乙烷法 由氯乙烷与硫氢化钠反应制得。C 2 H 5 Cl+NaSH→C 2 H 5 SH+NaCl 此法工艺简单,收率较高,缺点是需要加压,对设备要求高,间断操作,劳动强度大,氯乙烷来源受限制。 (3)乙醇(或乙烯)法 由硫化氢气体在催化剂存在下与乙醇蒸气或乙烯进行反应制得。C 2 H 5 OH+H 2 S→C 2 H 5 SH+H 2 O 此法工艺简单,原料易得,可以降低成本,产品纯度高,并能实现连续生产。主要缺点是反应温度高,硫化氢剧毒,并对设备有较强的腐蚀性。
  • 用途一:用于农药中间体、警戒气
  • 用途二:乙硫醇是一种重要的农药中间体,用于合成有机磷杀虫剂甲拌磷、乙拌磷、异丙磷、内吸磷、甲基内吸磷及除草剂烯禾啶等,此外,还可用作试剂及气体的加臭味剂、液体燃料添加剂,以及用于医药合成。
