Abstract: In continuous gas phase oxidn. of C3H6 to acrolein (I) and/or acrylic acid (II) with heterogeneous catalyst in an oxidn. reactor, the charge gas mixt. (III) contains only inert diluent gas(es) (IIIA) in addn. to C3H6 and O2 and (pt. of) (IIIA) is sepd. from the prodn. gas mixt. and recycled to the oxidn. reactor. The novelty is that (IIIA) consists of over 85 vol. % 1-5C satd. hydrocarbon(s).

Abstract: Continuous gas phase partial oxidn. of an organic cpd. (I) with heterogeneous catalyst in an oxidn. reactor uses a charge gas mixt. contg. (I) O2 and an inert diluent gas (II), which consists partly of combustible gases (IIA). The novelty is that the (IIA) fraction of (II) in the prod. gas stream leaving the oxidn. reactor is not recycled to partial oxidn. but used in another chemical reaction.

Abstract: Process for regenerating spent multimetal oxide oxidation catalysts from catalytic gas-phase oxidations of lower organic compounds, which catalysts, unspent, contain as base constituents the elements Mo, W, V and Cu in oxide form, by the action of oxidising agents and of solubilising aqueous ammonia containing added acetic acid and/or the ammonium salt thereof and subsequent drying and calcination in which, within the process, the content of the metallic constituents is quantitatively determined and supplemented to the respective original value.
