In chemistry, disulfate or pyrosulfate is the
anion with the molecular formula S
2O2−
7. Disulfate is the IUPAC name.
[1]
It has a
dichromate-like structure and can be visualised as two corner-sharing SO4
tetrahedra, with a bridging oxygen atom.
[2]
In this anion, sulfur has an
oxidation state of +6. Disulfate is the
conjugate base of the hydrogen disulfate (hydrogen pyrosulfate) ion HS
2O−
7, which in turn is the conjugate base of
disulfuric acid (pyrosulfuric acid).
Industrial production of sulfate ester-based surfactants involves the reaction ( sulfation) of fatty alcohols with sulfur trioxide. For example, dodecyl alcohol is sulfated using sulfur trioxide. The reaction proceeds by initial formation of the pyrosulfate:
Several million tons are produced annually. [3]
