| Section2 = | Section3 = | Section7 = }} Tungsten dichloride dioxide is the chemical compound with the formula WO2Cl2. It is a yellow-colored solid. It is used as a precursor to other tungsten compounds. Like other tungsten halides, WO2Cl2 is sensitive to moisture, undergoing hydrolysis. ==Preparation== WO2Cl2 is prepared by ligand redistribution reaction from tungsten trioxide and tungsten hexachloride: : 2 WO3 + WCl6 → 3 WO2Cl2 Using a two-zone tube furnace, a vacuum-sealed tube containing these solids is heated to 350 °C. The yellow product sublimes to the cooler end of the reaction tube. No redox occurs in this process. An alternative route highlights the oxophilicity of tungsten: :WCl6 + 2 O(Si(CH3)3)2 → 3 WO2Cl2 + 4 ClSi(CH3)3 This reaction, like the preceding one, proceeds via the intermediacy of WOCl4. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Tungsten dichloride dioxide」の詳細全文を読む スポンサード リンク
