What Is Cyclopentanone Cas 120-92-3
- Cyclopentanone is also called AdipicKetono. Colorless transparent oily liquid. It has a special ethereal and slightly mint-like smell. Relative molecular mass 84.12. Relative density 0.9487. Melting point -51.3℃. Boiling point: 130.6℃, 23~24℃ (1.333×103Pa). Refractive index 1.4366. Flash point 30℃. Chemicalbook is insoluble in water and soluble in ethanol, ether and acetone. It is narcotic in high concentrations. It can be obtained by oxidation of cyclopentanol. Or it can be obtained by heating adipic acid in the presence of barium hydroxide. Cyclopentanone is easy to polymerize, especially in the presence of acid. Under heating, the following dehydration reactions can be carried out to generate 2-cyclopentylenecyclopentanone and 2′-cyclopentylene-2-cyclopentylenecyclopentanone respectively.

Application
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.
