Cyclohexanone Usage And Synthesis |
Chemical properties | Cyclohexanone is a colorless, clear liquid with soil smell; its impure product appears as light yellow color. It is miscible with several other solvents. easily soluble in ethanol and ether. The lower exposure limit is 1.1% and the upper exposure limit is 9.4%. Cyclohexanone may be incompatible with oxidizers and nitric acid. Cyclohexanone is a primarily used in industry, up to 96%, as a chemical intermediate in the production of nylons 6 and 66. Oxidation or conversion of cyclohexanone yields adipic acid and caprolactam, two of the immediate precursors to the respective nylons. Cyclohexanone can also be used as a solvent in a variety of products, including paints, lacquers, and resins. It has not been found to occur in natural processes. |
Application | Cyclohexanone is mostly captively consumed, either isolated or as a mixture, in the production of nylon intermediates (adipic acid and Caprolactam). Around 4% is consumed in markets other than nylon, such as solvents for paints, dyes and pesticides. Cyclohexanone is also used in the manufacture of pharmaceuticals, films, soaps and coatings. Fibrant is one of the largest producers of Cyclohexanone, a raw material used in the production of Caprolactam. |
Uses | Cyclohexanone is an important chemical raw material, being the major intermediates of making nylon, caprolactam and adipic acid. It is also an important industrial solvent, for example, for paints, especially for those containing nitrocellulose, vinyl chloride polymers and their copolymers or methacrylate polymer paints. Used as an excellent solvent for pesticides such as organophosphate insecticide. It is used as a solvent for dyes, viscous solvents for piston aviation lubricants, solvents for greases, waxes and rubbers. Also used as leveling agent for dyeing and fading silk; degreasing agents for polishing metal; wood coloring paint; also used for cyclohexanone stripping, decontamination and spot removal. Cyclohexanone and cyanoacetic acid can have condensation reaction to generate cyclohexylidene acetic acid, and then followed by elimination and decarboxylation to get cyclohexene acetonitrile, and finally giving cyclohexene ethylamine by hydrogenation [3399-73-3]. Cyclohexene ethylamine is a intermediate for some drugs. |
Production method | In the 1940s, the industrial production of cyclohexanone mainly applied hydrogenation of phenol to generate cyclohexanol, followed by dehydrogenation to give cyclohexanone. In the 1960s, with the development of petrochemical industry, the cyclohexane oxidation production method gradually dominated. In 1967, the one step method of phenol hydrogenation, developed by the Netherlands National Mining Company (DSM) was industrialized. This method has short production process, good product quality and high yield, but the raw materials of phenol and catalyst are expensive, so the majority of the industry still adopts the cyclohexane oxidation method. 1. Phenol method takes nickel as a catalyst; first apply hydrogenation of phenol to give cyclohexanol, followed by dehydrogenation to give cyclohexanone using zinc as the catalyst for zinc. 2. Cyclohexane oxidation method uses cyclohexane as the raw material; first apply non-catalyst condition; use oxygen-rich air for oxidation to give cyclohexyl hydroperoxide, followed by decomposition into the mixture of cyclohexanol, cyclohexanone, alcohol and ketone in the presence of tert-butyl chromate catalyst; further apply a series of distillation refinement to get qualified products. Raw material consumption quota: cyclohexane (99.6%) 1040kg / t. 3. Benzene hydrogenation oxidation method; benzene subjects to hydrogenation (with hydrogen) at 120-180 ℃ in the presence of nickel catalyst to generate cyclohexane; cyclohexane has oxidation reaction with air at 150-160 ℃, 0.908MPa to obtain the mixture of cyclohexanol and cyclohexanone; separate them to obtain the cyclohexanone product. Cyclohexanol is dehydrogenated at 350-400 ° C in the presence of a zinc-calcium catalyst to produce cyclohexanone. Raw material consumption quotas: benzene (99.5%) 1144kg / t, hydrogen (97.0%) 1108kg / t, caustic soda (42.0%) 230kg / t. |
Description | Cyclohexanone, a colorless liquid is a cyclic ketone. It is an important building block for the synthesis of a variety of organic compounds. Majority of the cyclohexanone synthesized is utilized as an intermediate in the synthesis of nylon. Used as a polyvinyl chloride (PVC) solvent, cyclohexanone caused contact dermatitis in a woman manufacturing PVC fluidotherapy bags. Cyclohexanone probably does not cross react with cyclohexanone resin. A cyclohexanone-derived resin used in paints and varnishes caused contact dermatitis in painters. |
Chemical Properties | Cyclohexanone is a water-white to slightly yellow liquid with a peppermint-like or acetone-like odor. The Odor Threshold is 0.12 0.24 ppm in air. |
Physical properties | Clear, colorless to pale yellow, oily liquid with a peppermint-like odor. Experimentally determined detection and recognition odor threshold concentrations were identical: 480 μg/m3 (120 ppmv) (Hellman and Small, 1974). |
Occurrence | Reported present in Cistus labdaniferus. |
Uses | Industrial solvent for cellulose acetate resins, vinyl resins, rubber, and waxes; solventsealer for polyvinyl chloride; in printing industry; coating solvent in audio and videotape production |
Uses | Cyclohexanone is used as an industrial solvent and paint remover. It acts as a precursor to nylon 6,6 and nylon 6 and cyclohexanone oxime, which gives caprolactam on rearrangement. Further, it is used as a chemical reaction medium, adhesives, sealants and agricultural products. |
Uses | Cyclohexanone is used in the productionof adipic acid for making nylon; in thepreparation of cyclohexanone resins; and asa solvent for nitrocellulose, cellulose acetate,resins, fats, waxes, shellac, rubber, and DDT.. |

The symptomsin guinea pigs were lacrimation, salivation,lowering of heart rate, and narcosis. Exposureto 4000 ppm for 4–6 hours was lethalto rats and guinea pigs. The oral toxicity of this compound waslow. Ingestion may cause narcosis and depressionof the central nervous system. It canbe absorbed through the skin.
