用degass的方法处理溶剂有专门的仪器吗？应该怎么操作呀？ uthenium trichloride trihydrate (1 g) was refluxed in dimethyl sulphoxide (5 ml) for 5 min. The volume was reduced to half in vacuo when addition of acetone (20 ml) gave a yellow precipitate. The yellow couifilex which separated was filtered off, washed with acetone and ether, and vacuum dried. DMSO在90度就开始分解，而它的沸点是189度，此反应说回流5分钟，如果加热到回流的话要加热到DMSO的沸点，在此温度下DMSO不就分解了吗？求各位大侠帮我分析下此反应可行吗？ 谢谢各位！ [ Last edited by liuln on 2007-9-18 at 18:22 ] |
