Title:

PROCESS FOR PREPARING PPBENZOQUINONE

Document Type and Number:

Japanese Patent JPS5412334

Kind Code:

A

Abstract:

p-Benzoquinone is prepared by oxidizing phenol with molecular oxygen or with a gas in which oxygen is present, in the liquid phase, in the presence of cuprous or cupric ions. The improvement resides in carrying out the reaction in the presence of a metal, in the metallic form, which is selected from the group consisting of nickel, iron, tin, cobalt, chromium, molybdenum, magnesium and copper. The resultant p-benzoquinone is useful as an industrial source of hydroquinone, which is employed in photography.
