In
chemistry, peroxycarbonate (sometimes peroxocarbonate, IUPAC name: oxocarbonate or oxidocarbonate) or percarbonate is a
divalent
anion with formula CO2−
4. It is an
oxocarbon anion that consists solely of
carbon and
oxygen. It would be the anion of a hypothetical
peroxycarbonic acid HO–CO–O–OH (sometimes peroxocarbonic acid).
[1]
[2] or the real hydroperoxyformic acid, HO-O-CO-OH (a.k.a. percarbonic acid, carbonoperoxoic acid, hydroxycarbonic acid).
The peroxycarbonate anion is formed, together with
peroxydicarbonate C
2O2−
6, at the negative
electrode during
electrolysis of molten
lithium carbonate.
[3]
Lithium peroxycarbonate can be produced also by combining
carbon dioxide CO2 with
lithium hydroxide in concentrated
hydrogen peroxide H2O2 at −10 °C.
[4]
Electrolysis of a solution of lithium carbonate at -30° to -40 °C yields a solution of the Lithium percarbonate, which can liberate iodine from potassium iodide instantaneously. The crystalline salt has not been isolated.
The peroxycarbonate anion has been proposed as an intermediate to explain the catalytic effect of CO2 on the oxidation of organic compounds by O2. [5]
The potassium and rubidium salts of the monovalent
hydrogenperoxycarbonate anion (aka. hydroxycarbonate, biperoxycarbonate) H–O–O–CO−
2 have also been obtained.
