    • The invention relates to a method for producing a catalyst-precursor containing vanadium, phosphorous and oxygen for the production of maleic acid anhydride by means of heterogeneous catalytic gas phase oxidation of a hydrocarbon having at least four hydrocarbon atoms by reacting vanadium pentoxide (I) in the presence of a primary or secondary, non-cyclic or cyclic, non-branched or branched, saturated alcohol having 3 - 6 carbon atoms (II) with one five or 3-valent phosphorous compound (III) by agitating in a temperature range of between 80 - 160 °C and subsequently filtration of the obtained suspension, wherein a filtration resistance of αH.θ of ≤50.1013 mPa.s/m2 is adjusted by (a) the manner in which the phosphorous compound (III) and the vanadium pentoxide (I) are brought together in the presence of the alcohol (II), (b) by the influence of an agitator power of between 0.01 0.6 W/kg suspension and/or (c) by the filtration in a temperature range of between 65 °C - 160 °C. The invention also relates to a catalyst-precursor obtained according to said method for producing a catalyst from the catalyst-precursor, a catalyst which can be obtained according to said method, in addition to a method for producing maleic acid anhydride on said catalyst.
    • 本发明涉及一种生产含钒,磷和氧的催化剂前体用于生产马来酸酐的方法,该方法通过使五氧化二钒(I)与五氧化二钒(I)反应,通过多相催化气相氧化具有至少四个烃原子的烃 (II)与一种五价或三价磷化合物(III)的伯或仲,非环状或环状,非支链或支链饱和醇通过在 然后过滤得到的悬浮液,其中αH.θ的过滤阻力≤50.1013mPa.s/ m2通过(a)磷化合物(III)和五氧化钒 (I)在醇(II)存在下聚集在一起,(b)通过0.01-0.6W / kg悬浮液之间的搅拌器功率和/或(c)通过65℃至65℃之间的温度范围 °C - 160°C。 本发明还涉及一种催化剂前体,该催化剂前体除了在所述催化剂上生产马来酸酐的方法之外,还根据由所述催化剂前体制备催化剂的所述方法获得,催化剂可根据所述方法获得。
