Process for decomposing a mixture containing cycloalkylhydroperoxide, which mixture includes an organic phase and an aqueous phase, wherein during the decomposition, at least one compound is present which meets the following parameters: A > 0.5 and B > -1.0 (1), A and B being dependent on Tb, , nd, r, .delta.d, .delta.p, .delta.h, .delta., µ and ET(30), where Tb is the normal boiling point (~C), is the density measured at 25 ~C (kg/m3), nd is the refractive index (-), r is the relative dielectric constant (-), .delta.d is the Hansen solubility parameter for a dispersion (MPa1/2), .delta.p is the Hansen solubility parameter for polarity (MPa1/2), .delta.h is the Hansen solubitity parameter for hydrogen bridges (MPa1/2), .delta. is the Scatchard- Hildebrant solubility parameter (MPa1/2), µ is the dipole moment (Debey) and ET(30) is the Lewis donor/acceptor property (kcal/mol).

L'invention concerne un procédé qui permet de décomposer un mélange contenant du cycloalkylhydroperoxyde, et comprenant une phase organique et une phase aqueuse. Durant la décomposition est présent au moins un composé satisfaisant aux équations suivantes: A > 0,5 et B > -1,0 (1), A et B dépendant de T¿b?, ?, n¿d?, ?¿r?, .delta.¿d?, .delta.¿p?, .delta.¿h?, .delta., µ et E¿T(30)?, où T¿b? est le point d'ébullition normal (·C), ? est la densité mesurée à 25 ·C (kg/m?3¿), n¿d? est l'index de réfraction (-), ?¿r? est la constante diélectrique relative (-), .delta.¿d? est le paramètre de solubilité de Hansen pour une dispersion (MPa?1/2¿), .delta.¿p? est le paramètre de solubilité de Hansen pour la polarité (MPa?1/2¿), .delta.¿h? est le paramètre de solubilité de Hansen pour les ponts hydrogène (MPa?1/2¿), .delta. est le paramètre de solubilité de Scatchard-Hildebrant (MPa?1/2¿), µ est le moment dipolaire (Debey) et E¿T(30)? est la propriété de donneur/accepteur de Lewis (kcal/mol).
