<unk>  (also known as oxocyclohexane, pimelic ketone, ketohexamethylene, cyclohexyl ketone or ketocyclohexane) is a six-carbon cyclic molecule with a ketone functional group. It is a colorless, oily liquid with an acetone-like smell. Over time, the color of the liquid changes to yellow.<unk>  is slightly soluble in water (5-10 g/100 ml), but miscible with the most common organic solvents.<unk>  is employed as an industrial solvent and as activator in oxidation reactions. It is also used in the production of adipic acid,<unk>  resins, caprolactam and nylon 6.  Lube Control Distributors produces a<unk> -based motor oil additive called LC20 (marketed for several years as Microlube).  In the engine environment,<unk>  has been found to perform well at reducing harmful acids and as a solvent.
