    Abstract: Se describe un metodo para producir aldehidos, acidos carboxilicos, y/o anhidridos de acido carboxilico, especialmente anhidrido ftalico. De acuerdo con dicho metodo de una corriente gaseosa que comprende un hidrocarburo aromatico y oxigeno molecular es dirigida por menos a traves de un lecho de un primer catalizador y un lecho de un segundo catalizador a temperatura elevada, el segundo catalizador que esta ubicado corriente abajo desde el primer catalizador en la direccion de flujo de la corriente gaseosa y que tiene una mayor actividad que el primer catalizador, El material cataliticamente activo del primer catalizador contiene por lo menos oxido de vanadio, oxido de titanio, y oxido de antimonio, la relacion entre el vanadio, el cual es clasificado como V2O5, y el antimonio, el cual es clasificado como Sb2O3, en el primer catalizador varia entre 3.5: y 5:1. De manera preferible, el trioxido de antimionio, en particulas que tiene un tamano de particular promedio 0.5 hasta 5 ??m es utilizado como la fuente de oxido de antimonio. En el primer catalizador. El metodo de la invencion permite que se obtengan los productos de oxidacion deseados en un gran rendimiento a traves de periodos prolongados.

    Abstract: A catalyst for gas-phase oxidations which comprises an inert support and a catalytically active composition comprising transition metal oxides applied thereto, or a precatalyst, is described. The (pre)catalyst is obtained by treating the inert support with an aqueous suspension or solution of the transition metal oxides or their precursor compounds, where the suspension contains a binder dispersion and the binder is a copolymer of an alpha-olefin and a vinyl-C 2 -C 4 -carboxylate whose vinyl C 2 -C 4 -carboxylate content is at least 62 mol %.

    Abstract: A description is given of a process for preparing aldehydes, carboxylic acids and/or carboxylic anhydrides, in particular phthalic anhydride, in which a gaseous stream comprising an aromatic hydrocarbon and molecular oxygen is passed at elevated temperature over a bed of a first catalyst and a bed which is made up of a second catalyst having a higher activity than the first catalyst and is located downstream of the first catalyst in the flow direction of the gaseous stream, wherein the catalytically active composition of the first catalyst comprises at least vanadium oxide, titanium dioxide and antimony oxide and the ratio of vanadium, calculated as V 2 O 5 , to antimony, calculated as Sb 2 O 3 , in the first catalyst is from 3.5:1 to 5:1. The source of antimony oxide used for the first catalyst is preferably particulate antimony trioxide having a mean particle size of from 0.5 to 5 mum. The process allows the desired oxidation products to be obtained in high yield over longer periods of time.
