The compound is the third member of the series C''n''O2 with odd ''n'', the first two members being carbon dioxide (CO2) and carbon suboxide (C3O2). The compound was described in 1988 by G. Maier and others, who obtained it by pyrolysis of 1,3,5-cyclohexanetrione (phloroglucin, the tautomeric form of phloroglucinol). It has also been obtained by flash vapor pyrolysis of 2,4,6-tris(diazo)cyclohexane-1,3,5-trione (C6N6O3). It is stable at room temperature in solution.〔 The pure compound is stable up to −96 °C, when it polymerizes.〔 == References == 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「Pentacarbon dioxide」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
