Process for preparing cumene which is used in the preparation of phenol

   
   

Disclosed is a method for the preparation of cumene by reacting isopropanol or a mixture of isopropanol and propene with benzene in the presence of a .beta.-zeolite catalyst having a SiO.sub.2 /Al.sub.2 O.sub.3 molar ratio greater than 10:1 that can be integrated in a process for preparing phenol, which comprises preparing cumene as described above, oxidizing cumene to cumene hydroperoxide, acid-catalyzed cleavage of cumene hydroperoxide to give phenol and acetone, and hydrogenating acetone to form isopropanol.

Показан метод для подготовки cumene путем реагировать isopropanol или смесь isopropanol и пропена с коксобензолом in the presence of катализатор beta.-qeolita имея коэффициент greater than 10:1 SiO.sub.2 /Al.sub.2 O.sub.3 молярный можно интегрировать в процессе для подготовлять фенол, который состоит из подготовлять cumene как описано выше, окисляя cumene к гидроперекиси cumene, кислот-katalizirovannoe расщепление гидроперекиси cumene для того чтобы дать фенол и ацетон, и ацетон водородом к isopropanol формы.
