Abstract
A process and a mixture for oxidizing an alkyl-aromatic compound comprises forming a mixture comprising the alkyl-aromatic compound, a solvent, a bromine source, a catalyst, and ammonium acetate; and contacting the mixture with an oxidizing agent at oxidizing conditions to produce an oxidation product comprising at least one of an aromatic aldehyde, an aromatic alcohol, an aromatic ketone, and an aromatic carboxylic acid. The solvent comprises a carboxylic acid having from 1 to 7 carbon atoms; and the catalyst comprises at least one of cobalt, titanium, manganese, chromium, copper, nickel, vanadium, iron, molybdenum, tin, cerium, and zirconium.
Claims13
A process for oxidizing an alkyl-aromatic compound comprising:
- forming a mixture comprising the alkyl-aromatic compound, a solvent, a bromine source, a catalyst, and ammonium acetate, wherein the amount of ammonium acetate ranges from about 1 wt % to about 100 wt %, relative to the weight of the solvent;
- and
- contacting the mixture with an oxidizing agent at oxidizing conditions to produce a solid oxidation product comprising at least one of an aromatic aldehyde, an aromatic alcohol, an aromatic ketone, and an aromatic carboxylic acid;
- wherein the solvent comprises a carboxylic acid having from 1 to 7 carbon atoms, and optionally water, and the catalyst comprises at least one of cobalt, titanium, manganese, chromium, copper, nickel, vanadium, iron, molybdenum, tin, cerium, and zirconium.
