What Is Cyclopentanol?
Cyclopentanol is an organic compound formed when one hydrogen atom in cyclopentane is replaced with a hydroxy group. Its CAS number is 96-41-3, with a molecular formula of C5H10O and a molecular weight of 86.13. It has a melting point of -19℃ and a boiling point of 139-140℃. At room temperature, cyclopentanol appears as a colorless to slightly yellow liquid with an unpleasant odor and a density of 0.949 g/mL. It is insoluble in water but soluble in alcohols, ethers, and acetone. Cyclopentanol is also known as cyclopentyl alcohol or hydroxycyclopentane.
Uses of Cyclopentanol
Cyclopentanol is primarily used as a general solvent and in the preparation of flavors and fragrances. It is also used as a raw material in the pharmaceutical and agrochemical industries. As a precursor to cyclopentanone, cyclopentanol can be converted to cyclopentanone using catalysts like TEMPO. This conversion is significant as cyclopentanone is a valuable compound for various industrial applications, including as a biodegradable alternative to environmentally harmful cleaning solutions such as CFCs and 1,1,1-trichloroethane.
Principle of Cyclopentanol
1. Properties of Cyclopentanol
Cyclopentanol is a flammable liquid with a flash point of 51°C and should be handled away from heat, sparks, and open flames. It is acutely toxic and requires proper protective equipment during handling. In case of fire, irritating, corrosive, and toxic gases may be released.
2. Chemical Reactions of Cyclopentanol
Cyclopentanol can be synthesized by adding water to cyclopentene in the presence of an acid catalyst. Conversely, dehydration of cyclopentanol yields cyclopentene and water.
Types of Cyclopentanol
Cyclopentanol is typically sold as a chemical reagent for laboratory use in various quantities, such as 25 g, 5 mL, 25 mL, 100 mL, and 500 mL. It can be stored at room temperature.
