VERFAHREN ZUR OXIDIERUNG VON BENZOL UND/ODER TOLUOL ZU PHENOL UND/ODER CRESOL |
摘要 |
The invention relates to the field of organic synthesis, more specifically to a method for the production of phenol and cresol by the direct selective oxidation of benzene and toluene with nitrous oxide in the presence of a heterogeneous catalyst. Commercial high-silica zeolites are first calcined at a temperature of 500-950° C. sufficient to dehydroxylate it. It is then modified by the addition of modifying agents-zinc ions or zinc oxide-by applying a zinc compound to it. The catalyst is then activated in air or an inert gas at 300-850° C. The mixture of benzene or toluene with the nitrous oxide is brought into contact with the modified catalyst at 225 to 500° C. |
