Procedure

According to the invention, it is possible that the mixture which comprises 4-pentenal, 3-methyl-2-butanone and cyclopentene oxide and is obtained as a by-product of the oxidation of cyclopentene to cyclopentanone is used directly in the oxidation in step (a) of the process according to the invention. However, it is also possible in principle that a mixture obtained as a by-product of the oxidation of cyclopentene to cyclopentanone is first treated suitably before use in step (a). For example, this mixture, before step (a), can be concentrated and/or the proportion of other components which disrupt step (a) and/or subsequent steps in the mixture can be reduced.
