108-94-1 Usage

Health Hazard

Inhalation of vapors from hot material can cause narcosis. The liquid may cause dermatitis.

Definition

ChEBI: A cyclic ketone that consists of cyclohexane bearing a single oxo substituent.

General Description

A colorless to pale yellow liquid with a pleasant odor. Less dense than water . Flash point 111°F. Vapors heavier than air. Used to make nylon, as a chemical reaction medium, and as a solvent.

Reactivity Profile

Cyclohexanone forms an explosive peroxide with H2O2, and reacts vigorously with oxidizing materials (nitric acid).

Chemical properties

Colorless, clear liquid with soil smell; its impure product appears as light yellow color. Easily soluble in ethanol and ether.

Purification Methods

Dry cyclohexanone with MgSO4,CaSO4, Na2SO4 or Linde type 13X molecular sieves, then distil it. Cyclohexanol and other oxidisable impurities can be removed by treatment with chromic acid or dilute KMnO4. More thorough purification is possible by conversion to the bisulfite addition compound, or the semicarbazone, followed by decomposition with Na2CO3 and steam distillation. [For example, equal weights of the bisulfite adduct (crystallised from water) and Na2CO3 are dissolved in hot water and, after steam distillation, the distillate is saturated with NaCl and extracted with Et2O which is then dried (anhydrous MgSO4 or Na2SO4), filtered and the solvent evaporated prior to further distillation.] FLAMMABLE [Beilstein 7 III 14, 7 IV 15.]

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.

Air & Water Reactions

Flammable. Soluble in water.

Fire Hazard

HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.

Chemical Properties

colourless liquid

Application

It is the raw material for the production of caprolactam and adipic acid; used as the solvents and diluent agents of paints, inks, synthetic resins and synthetic rubber; also used as leather degreasing agent.
Used as organic solvent;
Raw materials and solvents of synthetic resin and synthetic fiber;
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.
The solvents for fibers, resins, rubbers, paraffins, shellac and DDT; for organic synthesis; it can dissolve many of the complexes formed by the elements and organic reagents; bismuth determination; extract rare metal such as uranium, thorium, cobalt and titanium.

Contact allergens

Used as a polyvinyl chloride 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
