In the case of a fire, all ignition sources should be removed, and alcohol-resistant foam, dry chemical or CO 2 should be used to fight. Soak up the spillage with dry materials such as dirt or combustible materials.Ĭyclohexanone has a low flash point therefore, fires can easily be ignited. You should also prohibit the leak from spreading into waterways, sewers, and basements. In the case of a spillage, the leak should be isolated at a minimum of 50 metres and avoid being walked through. An instability rating of 0 indicates that it is “normally stable, even under fire conditions”.
Heat, sparks, or flames can and create vapours that are heavier than air and will travel to the source of the ignition and surrounding areas. It has an NFPA fire rating of 3 and “can be ignited under almost all ambient temperature conditions”. Excessive exposure to the eyes, nose and skin can cause similar effects such as irritation, drowsiness, and unconsciousness. If inhaled, it can irritate the throat and respiratory passages, causing headaches and nausea. Handling, storage and distribution Hazards and toxicityĬyclohexanone has an NFPA health rating of 1 and “can cause significant irritation”. Demand for it is still growing, especially in China, and several new production plants have come on-line in the past few years in order to help meet this demand. Worldwide, thousands of tonnes of cyclohexyl ketone are produced annually. Other methods include the catalytic dehydrogenation of cyclohexanol: This reaction is one of the primary commercial bulk manufacturing methods, the other being the hydrogenation of benzene (in a closed system). There are several methods of manufacturing cyclohexanone, one of which being the catalytic hydrogenation of phenol:Īnother method is via the catalytic air-oxidation of cyclohexane, typically in the presence of cobalt crystals: Water Solubility: 50 to 100 mg/mL at 64° Fĭensity: 0.945 at 68 ☏ How is cyclohexanone made? Synonyms: Ketohexamethylene, oxocyclohexane, sextone, pimelic ketone, pimelin ketone, cyclohexyl ketone, Hydrol-O, anone, CYC.īoiling Point: 312.1 ° F / 155.6 at 760 mm Hg Technical PropertiesĬhemical and physical properties of cyclohexanone: It occurs naturally in crude oils and is also produced synthetically, in large quantities, as it is a key intermediate in the production of nylon. It is slightly soluble in water, completely miscible with common solvents and reacts with oxidants such as nitric acid. It is a sixcarbon cyclic molecule belonging to the class of cyclic ketones (organic compounds) with the formula C 6H 10O.
Cyclohexanone (also known as oxocyclohexane, pimelic ketone, cyclohexyl ketone, and CYC) is a clear oily liquid that has a colourless to light yellow tinge and a pungent odour.
