摘要： A catalyst for the oxidation of hydrocarbons comprising a phosphorus and vanadium mixed oxide wherein the catalyst prepared by using an organic medium can be recycled according to our process thus conserving up to ninety percent of the vanadium used in the preparation of the catalyst. The mixed oxide can also be promoted by a transitional element of the IV and V period of the periodic table. These catalysts are particularly useful for the oxidation of C.sub.4 hydrocarbons to maleic anhydride.

摘要： Catalytic liquid phase molecular oxygen oxidation of methyl-substituted aromatic hydrocarbons having two or more methyl-substituents on adjacent ring carbon atoms in acetic acid reaction medium have, in general, resulted in a substantial production of the desired ortho-oriented di-, tri-, and higher polycarboxylic substituted aromatic acids but also in the co-production of substantial amounts of oxygenated intermediates including methyl-substituted mono- and non-ortho polycarboxylic acids. Several theories have been proposed, including inherent auto-inhibiton, for such incomplete oxidations.

摘要： This invention relates to the neat air oxidation of liquid o-xylene in a continuous manner in a single step to overcome the limited conversion of the process of British Patent Specification No. 856,245 or of the process of U.S. Pat. No. 3,920,735. More specifically this invention overcomes the limited conversion of o-xylene by its single step air oxidation in the presence of catalysis provided by ions of cobalt, manganese and bromine not only by maintaining the proper relationship of temperature, pressure and free water concentration in the reaction mixture to minimize the conversion of o-phthalic acid to its intramolecular anhydride but also by conducting the oxidation in the presence of small amounts of acetic or benzoic acid to make miscible the otherwise immiscible liquid phases of liquid o-xylene and liquid o-phthalic acid containing components of catalysis and free liquid water.
