|Section2= |Section3= }} Triphosgene (bis(trichloromethyl) carbonate (BTC), C3Cl6O3) is a chemical compound that is used as a safer substitute for phosgene, because at room temperature it is a solid crystal, as opposed to phosgene which is a gas. Triphosgene crystals decompose above 200 °C ==Preparation== This compound is commercially available. It is prepared by exhaustive free radical chlorination of dimethyl carbonate:〔 :CH3OCO2CH3 + 6 Cl2 → CCl3OCO2CCl3 + 6 HCl Triphosgene can be easily recrystallized from boiling hexanes to yield pure white crystals. 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「triphosgene」の詳細全文を読む スポンサード リンク
