Шаблон:Chembox Dodecahydroxycyclohexane is an organic compound with molecular formula Шаблон:Chem2 or Шаблон:Chem2 or Шаблон:Chem2. It is a sixfold geminal diol with a cyclohexane backbone and can be regarded as a sixfold hydrate of cyclohexanehexone (Шаблон:Chem2).

Dihydrate

The dihydrate Шаблон:Chem2 can be crystallized from methanol as colorless plates or prisms, that decomposes at about 100 °C.[1]

This compound was synthesized by J. Lerch[2] in 1862 by oxidation of benzenehexol Шаблон:Chem2 or tetrahydroxy-p-benzoquinone Шаблон:Chem2 and characterized by R. Nietzki and others in 1885,[3] although the product was for a long time assumed to be hexaketocyclohexane with water of crystallization (Шаблон:Chem2).

Indeed, this product is still commonly marketed as cyclohexanehexone octahydrate, hexaketocyclohexane octahydrate, triquinoyl octahydrate and similar names. Its true nature was suspected since the 1950s or earlier,[4] but was confirmed by X-ray diffraction analysis only in 2005.[5]
