WebCyclopentylidene derivatives of pentoses have been prepared in moderate yields by treatment of the free sugars with cyclopentanone in the presence of copper (II) sulphate and sulphuric acid. D-Xylose formed the diacetal (11) (also used in Scheme 3 below), whereas from D-ribose the 2,3-monoacetal (12) was obtained. WebCyclopentanone has a relatively low boiling point due to its small size and relatively weak intermolecular forces. It is a volatile compound that can easily evaporate at room temperature. Cyclopentanone melting point. Cyclopentanone has a melting point of approximately -47°C.
