    摘要: The invention relates to a coated catalyst which comprises (a) a support body, (b) a shell comprising a catalytically active multimetal oxide comprising molybdenum and at least one further metal, where the shell is made up of multimetal oxide particles having a d50 of from 6 to 13 μm, and can be obtained by (i) production of a multimetal oxide precursor composition comprising molybdenum and at least one further metal, (ii) production of a shaped body from the multimetal oxide precursor composition, (iii) calcination of the shaped body composed of the multimetal oxide precursor composition to produce a multimetal oxide composition, (iv) milling of the shaped body composed of multimetal oxide composition to form multimetal oxide particles having a d50 of from 6 to 13 μm, (v) coating of the support body with the multimetal oxide particles, (vi) thermal treatment of the coated support body.
