  • 上游原料:乙醇 --> 五硫化二磷
  • F:10-13-23
  • 方法二:由乙醇与五硫化二磷反应而得。
  • MOL 文件:298-06-6.mol
  • Sigma Aldrich:298-06-6(sigmaaldrich)
  • 方法一:乙基硫化物由无水乙醇与五硫化二磷反应而得。 原有工艺所得产品含量85％～87％，收率为85％左右。新工艺使用催化剂，使收率和产品质量大为提高。该工艺过程为：按一定比例在搅拌下将五硫化二磷加到上批硫化物的母液中，加适量催化剂，减压下加入无水酒精，温度控制在50～65℃(最高不超过80℃)，15～25min内加完，继续在50～65℃保温反应10～20min后冷却到45℃以下，静置，出料得产品。反应中生成的硫化氢气体用碱液吸收。收率90％～92％，产品含量91％～93％。
  • 下游产品:甲拌磷 --> 灭克磷 --> 伏杀磷 --> 乙硫磷
  • 用途一:O，O-二乙基二硫代磷酸酯简称乙基硫化物，也是一种重要的农药中间体，可用于制备有机磷杀虫剂如甲拌磷、特丁硫磷、伏杀硫磷等，并可通过氯化合成另一个有机磷中间体O，O-二乙基硫代磷酰氯。
  • 有极强的腐蚀性，高温分解， 工业品有硫化氢臭味。
