It comes in the form of a colourless, hygroscopic, nonflammable, highly reactive gas characterized by a musty odour.〔(CDC - NIOSH Pocket Guide to Chemical Hazards )〕 The most common form of this substance is hexafluoroacetone sesquihydrate (1.5 H2O), which is a geminal diol. ==Synthesis and reactions== (CF3)2CO is prepared in a two step process from perfluoropropene. In the first step KF catalyzes the reaction of the alkene with elemental sulfur to give the 1,3-dithete ()2. This species is then oxidized by iodate to give (CF3)2CO. 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「hexafluoroacetone」の詳細全文を読む スポンサード リンク
