|Section2= |Section3= }} Propylene carbonate (often abbreviated PC) is an organic compound with the formula CH3C2H3O2CO. It is a carbonate ester derived from propylene glycol.〔(WebBook page for propylene carbonate )〕 This colorless and odorless liquid is useful as a polar, aprotic solvent.〔 Propylene carbonate is chiral but is used exclusively as the racemic mixture. ==Preparation== Although many organic carbonates are produced using phosgene, propylene and ethylene carbonates are exceptions. They are mainly prepared by the carbonation of the epoxides:〔 :CH3CHCH2O + CO2 → CH3C2H3O2CO The process is particularly attractive since the production of these epoxides consumes carbon dioxide. Thus this reaction is a good example of a green process. The corresponding reaction of 1,2-propanediol with phosgene is complex, yielding not only propylene carbonate but also oligomeric products. 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「propylene carbonate」の詳細全文を読む スポンサード リンク
