Tricarbonate : ウィキペディア英語版 | Tricarbonate In organic chemistry, a tricarbonate is a compound containing the divalent () functional group, which consists of three carbonate groups in tandem, sharing two oxygen atoms. These compounds can be viewed as double esters of a hypothetical tricarbonic acid, HO-(C=O)-O-(C=O)-O-(C=O)-OH. An important example is di-''tert''-butyl tricarbonate (H3C-)3C-C3O7-C(-CH3)3, a chemical reagent (colorless prisms that melt at 62–63 °C with decomposition, soluble in pentane).〔Barry M. Pope, Yutaka Yamamoto, and D. Stanley Tarbell (1977), ("Di-tert-Butyl Dicarbonate" ). ''Organic Syntheses'', Vol. 57, p.45; Coll. Vol. 6 (1988) p.418〕 The term "tricarbonate" is sometimes used for salts that contain three carbonate anions in their stoichiometric formula, such as cerium tricarbonate Ce2(CO3)3. ==See also==
