Cyclopentanone (CAS: 120-92-3) is mainly used for the manufacturing of pharmaceuticals, flavor industries, biological agents, pesticides and rubber additives. Aldehydes, ketones can react with diazoalkane and have the nitrogen atoms lost, generating two carbonyl compounds and epoxy compounds. When the aldehydes, ketones molecules contain electron-withdrawing groups, the reactivity is increased will boost the generation of the epoxy compound. The ketone molecule, with the increase of the hydrocarbon group, also mainly generates epoxy compound. Cyclic ketones, instead, will have ring expansion reactions. The bigger the hydrocarbyl group of the diazoalkane is, the more carbonyl compounds can be obtained.
Cyclopentanone is used as an intermediate in the synthesis of rubber adhesives, synthetic resins, pharmaceuticals and biologically active compounds. It acts as precursor for the preparation of Cyclopentamine and also pentethylcyclanone, Cyclopentobarbital. It is a useful laboratory reagent and is used as thinner for epoxies. It can also be used as a solvent in paint and varnish removers and for electronic applications. As a dry cleaning agent, it is used for oil extraction. It is also involved in the preparation of Cyclopentanone derivatives like cyclopenylamine and cyclopentanol which find application in the perfume industry.
It is flammable in case of fire, high temperature and with burning producing irritated smoke.
Cyclopentanone polymerizes easily, especially in the presence of acids. Can react with oxidizing materials, i.e. hydrogen peroxide.
Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
Moderately toxic by intraperitoneal and subcutaneous routes. A skin and severe eye irritant. Dangerous fire hazard when exposed to heat or flame; can react with oxidizers. To fight fire, use alcohol foam, foam, CO2, dry chemical. Potentially explosive reaction with hydrogen peroxide + nitric acid. When heated to decomposition it emits acrid smoke and fumes.
