In organic chemistry, a dicarbonate is a compound containing the divalent () or 2• functional group, which consists of two carbonate groups sharing an oxygen atom. These compounds can be viewed as double esters of a hypothetical dicarbonic acid, or HO-(C=O)-O-(C=O)-OH. Two important examples are dimethyl dicarbonate H3C-C2O5-CH3 and di-''tert''-butyl dicarbonate (H3C-)3C-C2O5-C(-CH3)3. It is one of the oxocarbon anions, consisting solely of oxygen and carbon. Dicarbonate salts are apparently unstable but may have a fleeting existence in carbonate solutions.> The term "dicarbonate" is sometimes used erroneously to refer to bicarbonate, the common name of the hydrogencarbonate anion ()− or organic group (). ==See also== *Oxalate *Peroxodicarbonate *Tricarbonate 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「Dicarbonate」の詳細全文を読む スポンサード リンク
