氧氯化硒合成路线

氧氯化硒上下游产品

氧氯化硒制备

1.使干燥的HCl气体与二氧化硒反应生成二氯代亚硒酸SeO2·2HCl,用浓硫酸使SeO2·2HCl脱水即可制得氯化氧硒。反应瓶为一已知重量的容积为150mL的圆底烧瓶,HCl气体导入管经过一容积为500mL的安全瓶后与反应瓶相连接。将50g SeO2置于反应瓶中,在隔绝湿气的条件下将经过仔细干燥的HCl气体通入反应瓶中,并不时摇晃反应瓶,直至SeO2吸收HCl全部变为SeO2·2HCl而溶解(理论增重33g)。向反应瓶中加入10mL浓硫酸,摇动反应瓶使其充分混合,并慢慢加温至50℃,这样处理10min使SeO2·2HCl脱水,已部分脱水的产物沉于下层。将液体转移至100mL分液漏斗中,使两层液体分离。向分离出的液体产物中再加入5mL浓硫酸,按同样的方法进行处理,直至液体不再发生分层为止。应注意的是脱水不够或脱水时使用的硫酸过多都会使产率降低。完全脱水的产物可溶解于浓硫酸,加热时形成澄清透明的溶液,未完全脱水时加入浓硫酸后摇动会发生浑浊,加热时分层。在蒸馏之前,产品中因含有SeCl2而为樱桃红色,应通入氯将其氯化,直至变为草黄色。这时SeCl2转变为SeCl4,SeCl4与SeO2反应生成SeOCl2。在隔绝湿气的条件下,用水流吸气泵抽真空蒸馏两次,为防止爆沸,蒸馏瓶中应插入一根毛细管。每次蒸馏最初的几毫升馏出物弃去,蒸馏至有大量SeO2积聚时停止。若产物不为微黄色,则应在第二次蒸馏前再通氯一次。最后将产品隔绝湿气转移至玻璃安瓿中,烧封后保存。
