Cyclopentanol, also known as hydroxycyclopentane, is a colorless oily liquid with a distinctive musty odor. Its relative molecular mass is 86.14, with a relative density of 0.9478. It has a melting point of -19°C and boiling points of 140.85°C, 56.4–57.4°C (at 4.533 × 103 Pa), and 53°C (at 1.333 × 103 Pa). The refractive index is 1.4530, and the flash point is 51°C. It is slightly soluble in water but soluble in ethanol. It forms an azeotropic mixture with water, containing 42% of this compound, with an azeotropic point of 96.3°C.

【Uses】Cyclopentanol is primarily used in the production of pharmaceutical raw materials, dyes, and fragrances. It also serves as a solvent for drugs and perfumes. 【Preparation Method】Cyclopentanone is obtained by dry distillation of adipic acid under the action of barium hydroxide, and then cyclopentanol is produced by hydrogenation with lithium aluminum hydride in **.
