Patent

CA 2274976

The present invention relates to an improved process for producing phenol and acetone by oxidizing cumene into technical cumene hydroperoxide (CHP) through catalytic cleavage of the CHP. According to the invention, the oxidation products are concentrated up to a cumene content ranging from 21 to 30 wt.% in the technical cumene hydroperoxide, and this mixture is used for the catalytic cleavage.

La présente invention concerne un procédé perfectionné pour la préparation de phénol et d'acétone par oxydation de cumène en vue d'obtenir un hydroperoxyde de cumène (CHP) de qualité technique, avec clivage catalytique du CHP. Dans ce procédé, les produits d'oxydation sont concentrés jusqu'à l'obtention d'une teneur en cumène de 21 à 30 % en poids dans l'hydroperoxyde de cumène de qualité technique, et ce mélange est utilisé pour le clivage catalytique.
