Document Type and Number:
WIPO Patent Application WO2001055073
Kind Code:
A3
Abstract:
The invention relates to a method for oxidizing o-xylol with oxygen, preferably mixed with an inert gas, especially air, while adding a catalyst, in order to produce a mixture of oxidation products of the o-xylol. The selectivity of the reaction can be increased by adding an aldehyde to the o-xylol.
