Cyclohexanehexone, also known as hexaketocyclohexane and triquinoyl, is an organic compound with formula C6O6, the sixfold ketone of cyclohexane. It is an oxide of carbon (an oxocarbon), a hexamer of carbon monoxide.
Cyclohexanehexone can be viewed as the neutral counterpart of the rhodizonate anion C
6. The singly charged anion C
6 has been detected in mass spectrometry experiments, formed by oligomerization of carbon monoxide through the formation of molybdenum carbonyls.
According to X-ray diffraction analysis, the reagent traded under the name "cyclohexanehexone octahydrate" or equivalent names is actually dodecahydroxycyclohexane dihydrate—the geminal diol derivative of the six ketone groups with an additional two molecules of water—a solid that decomposes at 95 °C.
In 1966, Howard E. Worne of Natick Chemical Industries patented compounds with formulas C10O8 and C14O10, which can be described as the fusion of two or three molecules of C6O6, claimed to be produced by the action of ultraviolet radiation on a hot water solution of the parent compound.
In the late 1940s, William J. Hale claimed that "triquinoyl", being a trimer of William Frederick Koch's glyoxylide, should be just as effective as the latter against "diabetes, arthritis, poliomyelitis, and even cancer". Even though there is no research supporting this claim (and Koch's glyoxylide preparations were found to be just distilled water), triquinoyl is still listed as an ingredient of some alternative medicine remedies.
