Benzenehexol, also calledhexahydroxybenzene, is anorganic compound with formulaC 6H 6O 6 orC 6(OH) 6. It is a six-foldphenol ofbenzene.[2][3] The product is also calledhexaphenol,[4] but this name has been used also for other substances.[5]
Like most phenols, benzenehexol can lose the sixH+ ions from thehydroxyl groups, yielding thehexaanionC 6O6− 6. Thepotassium salt of this anion is one of the components ofLiebig's so-called "potassium carbonyl", the product of the reaction ofcarbon monoxide with potassium. The hexaanion is produced by trimerization of theacetylenediolate anionC 2O2− 2 when heating potassium acetylenediolateK 2C 2O 2.[9] The nature ofK 6C 6O 6 was clarified[10] byRudolf Nietzki andTheodor Benckiser [de] in 1885, who found that itshydrolysis yielded benzenehexol.[11][12]
Hexahydroxy benzene forms esters such as the hexaacetateC 6(-O(CO)CH3)6 (melting point 220 °C) and ethers likehexa-tert-butoxybenzeneC 6(-OC(CH3)3)6 (melting point 223 °C).[9]
