Cyclohexanone is an organic compound with the chemical formula C6H10O, which is a saturated cyclic ketone with the carbonyl carbon atom included in a six-membered ring. It is a colorless transparent liquid with an earthy flavor and a minty flavor when it contains traces of phenols. Cyclohexanone in impure state is light yellow, with storage time to produce impurities and strengthen color from water white to gray yellow, with a strong pungent odor. Mixed with air the explosive pole is the same as the open chain saturated ketone. In industry, it is mainly used as raw materials and solvents for organic synthesis, such as it can dissolve cellulose nitrate, coatings, paints, etc.
