|Section2= |Section3= |Section7= |Section8= }} Selenium oxydichloride is the inorganic compound with the formula SeOCl2. It is a liquid with a high dielectric constant (55) and high specific conductance, and for these reasons is an attractive solvent. Structurally, it is a close chemical relative of thionyl chloride SOCl2 and DMSO as a donor solvent. ==Preparation and reactions== Selenium oxydichloride can be prepared by several methods, and a popular one involves the conversion of selenium dioxide to dichloroselenious acid followed by dehydration: :SeO2 + 2 HCl → Se(OH)2Cl2 :Se(OH)2Cl2 → SeOCl2 + H2O The original synthesis involved the redistribution reaction of selenium dioxide and selenium tetrachloride. The compound hydrolyzes readily. 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「selenium oxydichloride」の詳細全文を読む スポンサード リンク
